2 Lignocellulose Structure and Uses

Lignocellulose is comprised of three main componentsthat is cellulose hemicellulose and lignin [21] (Figure 1)Cellulose is the high molecular weight linear polymer of D-glucopyranose units linked together by 120573-(lrarr 4)-glycosidicbonds with cellobiose dimer being the repeating unit Thecellulose chains are hydrogen bonded to each other makinga bundle of microfibrils which further aggregate together

to make cellulose fibrils [22] The structure shows variationsfrom amorphous to crystalline regions The cellulose fibrilsare packed in the cell wall in a matrix of hemicelluloses andlignin [23] Hemicelluloses are linear or branched hetero-polysaccharides composed of D-xylose L-arabinose D-gal-actose D-glucose or D-mannose sugars with or withoutdifferent uronic acids and may include xylans mannans glu-cans glucuronoxylans arabinoxylans glucomannans galac-tomannans galactoglucomannans 120573-glucans and xyloglu-cans [10 24] The branching and composition vary amongdifferent plant sources Xylan the polymer of xylose is themost abundant hemicellulosic component [10] Lignin is avery complex polyphenolic heteropolymer primarily madeup of three phenyl propionic alcohol monomers that is p-coumaryl alcohol coniferyl alcohol and sinapyl alcohol [25]

Enzyme Research 3

Celluloses hemicelluloses and lignin are packed closelyin a crisscross network and glued with the help of a variety ofnoncovalent and covalent linkages Lignin acts as a cement-ing agent and provides structural support It also providesimpermeable barrier to the enzymes making whole structurerobust and resistant [22] Cellulose is the most abundantpolymer of plant cell walls (35ndash50) followed with hemicel-lulose (20ndash35) and lignin (10ndash25) [10]

Cellulose is used for many purposes such as in manufac-turing of paper and textile fabric in production of biofuel(from fermentable sugar glucose) as inert packing and insu-lating material and in food and drugs as base and stabilizer[26] Hemicelluloses are utilized in a range of applicationsBiodegradability and nontoxicity of hemicelluloses enable itto be used as dietary fibre [27] and as edible coating overfoodstuffs for their stabilization Mannans have cholesterollowering properties [28] Xyloglucans and 120573-glucans are usedin ice-creams and other foods due to their gelling stabilizingand thickening effects Adhesive properties are used in papermaking Hemicelluloses are rich source of xylose sugarswhich are fermented to ethanol fuel [29] Characteristics oflignin also make it an important component used in the pro-duction of a wide range of value added products [30] Lignincan be used as a source of activated carbon and phenol usefulin the synthesis of wide array of chemicals [31] and to producebiocomposites [32] or polymers [33] which can replace plasticbased products either partially or completely It can be usedas binder in small scale processes and as filler in place ofoil based carbon fibres Biosorption properties of lignin [34]are also foreseen as a potent application Furthermore ligninis a rich source of energy [35] Thus lignocellulose is arepertoire of industrially useful components But the struc-tural characteristics of the cell wall or lignocellulose are suchthat the extraction of individual component to homogeneityand purity is a difficult task requiring specific chemical orbiological procedures Also many applications are based ondegradation products of the cellulose hemicellulose or ligninmaking hydrolysis an essential requirement Hydrolysis canbe mediated both chemically and enzymatically Chemicalmethods involve use of expensive chemicals harsh condi-tions and have certain other limitations Enzymatic methodsare therefore preferred and lignocellulolytic enzymes playvery important role in these applications Presently biomassutilization is executed through biorefinery which aims atsignificant utilization of all components generating leastpossible amount of waste When one constituent of biomassis utilized others are simultaneously used for production ofvaluable products During biofuel production sugars fromhemicellulose and cellulose components are used in ethanolformation and lignin residue left is used for power generationor in other uses of lignin Lignocellulases perform importantfunctions in biorefinery processes also

3 Lignocellulolytic EnzymeSystems in Actinomycetes

31 Cellulases Cellulolytic enzymes are a group of glycosylhydrolases classified into different families depending on

their sequence homologies The mechanisms of action andsubstrate specificities vary among different cellulases butthey are generally divided into exoglucanases (EC 32174)endoglucanases (EC 3214) cellobiohydrolases (EC 32191)and 120573-glucosidases (EC 32121) [36 37] Exoglucanasesact on reducing or nonreducing ends of cellulose chainsreleasing glucose units whereas endoglucanases hydrolyse120573-14-glycosidic bonds randomly inside the cellulose chainsreleasing dextrans of variable lengths [38] Cellobiohydro-lases cleave glycosidic bonds at nonreducing ends andrelease cellobiose units [39] These enzymes are particularlyimportant in hydrolysing crystalline cellulose because oftheir processivity [36] 120573-glucosidases enzymes take part inhydrolysis of cellobiose units to monomeric glucose [38]Complete hydrolysis of cellulose involves synergistic effect ofall these enzymes showing synergy between endoglucanasesand exoglucanases (endo-exo synergy) exoglucanases actingon the reducing and nonreducing ends (exo-exo synergy)between cellobiohydrolases and 120573-glucosidases and betweencatalytic and carbohydrate binding domains [39] Figure 2shows schematic presentation of enzymatic hydrolysis of cel-lulose polymer

Microbial cellulase systems are either complexed ornoncomplexed [39] Complexed systems known as cellulo-somes are characteristics of anaerobic bacteria consisting ofmultienzyme complex protuberances from cell surface stabi-lized by dockerin and adhesion proteins In aerobic bacteriaincluding most of the actinomycetes cellulases are noncom-plexed or free and are secreted extracellularly using specificsecretion pathways

Among cellulase producing actinomycetes CellulomonasfimiMicrobispora bispora andThermobifida fusca have beenstudied extensively [6 39] Thermobifida fusca is a ther-mophilic spore forming actinomycete [6] The genome ofT fusca consists of 36 billion bp in a single circular chro-mosome with 3117 coding sequences and has 675 G+Ccontent which stabilizes DNA in extreme temperature condi-tions [40] The genome encodes for 36 glycoside hydrolasesdistributed in 22 GH (glycoside hydrolases) families [40]Cellulase system of T fusca is comprised of six extracellularcellulases (4 endocellulases and 2 exocellulases) and oneintracellular 120573-glucosidase [6 40ndash42] Each enzyme has aseparate catalytic and carbohydrate binding domain bothlinked together with a linker peptide [36 41] Carbohydratebinding domains in all six cellulases belong to the samefamily that is 2CBD [41] The catalytic domains howeverare different in all enzymes belonging to different familieswith Cel5A and Cel5B from GH family 5 Cel6A and Cel6Bfrom GH family 6 Cel9A and Cel9B from GH family 9 andCel48A from family 48 [43] Cel5A Cel5B Cel6A and Cel9Bare endocellulases and do not show processivity [36 40 41]Cel6B and Cel48A are processive exocellulases which act atnonreducing and reducing ends respectively Cel9A is a novelprocessive cellulase with both exo- and endocellulase actionsstarting exohydrolysis from the nonreducing end [36] Theposition of CBD varies in different cellulases which is N-terminus in Cel5A Cel6B and Cel48A and C-terminus inCel6A Cel9A and Cel9B [41] Sequence studies of catalyticdomains have revealed less than 31 similarity between

Cellulomonas fimi is a facultative anaerobe but it does notconsist of cellulosomes of cellulolytic anaerobes rather it pro-duces free cellulases [46] Similarly facultatively anaerobicCellulomonas flavigena also secrets free cellulases [46] Bothcarry out efficient hydrolysis of celluloses and hemicelluloses

The cellulase enzyme systems in Cellulomonas fimi also con-sist of six cellulases [39] that is three endocellulases (CenACenB and CenD) two exocellulases (CbhA and CbhB) anda processive endocellulase CenC [41 46] All these enzymeshave activities similar to that inT bifida with same families ofCBDs (2CBD) and catalytic domains but different sequences[41 47] These cellulases are primarily secreted by sec depen-dent pathway [46] and therefore do not require intracellularfolding or cofactors for their activity InC fimiATCC484 andC flavigena ATCC 482 another enzyme GH94 (cellobiosephosphorylase) has also been discovered [46] Microbisporabispora also shows synthesis of six different cellulases show-ing exo-exo and endo-exo synergism [6] Genomic studiesof Streptomyces sp SirexAA-E (ActE) isolated from pine-boring woodwasp Sirex noctilio have also shown genes forGH48 (CBH activity) GH74 (endocellulase) and CDB33[48] Streptomyces coelicolor consisted of 221 carbohydrateactive enzymes (CAZy) or 154 glycosyl hydrolases (GHs)encoded within 86 billion bp long genome [48]

The expression of cellulolytic genes in T bifida is inducedby cellobiose whereas easily utilizable sugar glucose showscatabolite repression as in most of the other cellulolyticmicrobes [49]The regulation of cellulolytic genes ismediatedby the CelR repressor which binds to a 9ndash14 bp palindrome

The extracellular cellulases are secreted by actinomycetesusing either one or both of the common bacterial systemsfor secretion of extracellular proteins that is sec generalsecretion system and sec independent twin-arginine translo-cation (TAT) systems The general Secretion route catalysestransmembrane translocation of proteins in their unfoldedconformation whereas Twin-arginine (TAT) system translo-cates secretory proteins in their native folded state InT bifidaboth of these systems were discovered whereas S coelicolormainly utilizes TAT systems for protein export [40]

32 Hemicellulases Hemicellulases are generally synthesisedalong with cellulases [36 39] Xylan and mannan are mostabundant components of hemicelluloses Complete hydroly-sis of xylan involves an enzyme system consisting of endo-14-120573-xylanases (EC 3218) 120573-D-xylosidases (EC 32137)120572-L-arabinofuranosidases (EC 32155) 120572-glucuronidases(EC 321139) acetyl xylan esterases (EC 31172) and fer-uliccoumaric acid esterases (EC 31173) Mannan is hydrol-ysed primarily by synergistic action of mannanases (EC32178) 120573-mannosidases (EC 32125) and 120572-galactosidases(EC 32122) [36 51] Mannanases hydrolyze 120573-14-glycosidicbonds internally 120573-mannosidase cleave 120573-14 linked man-nose from nonreducing ends and 120572-galactosidase removesterminal D-galactosyl residues linked by 120572-16 linkages [52]Degradation of mannan and xylan also enhances cellulosehydrolysis as they are known to inhibit cellulase activities[36]

Most of the hemicellulases belong to glycosyl hydrolasesfamilies however some enzymes involved in hemicellulosehydrolysis belong to glycosyltransferases (EC 241x) [39]Xylanases hydrolysing internal 120573-14-glycosidic bonds areclassified into GH families 5 7 8 10 11 and 43 120573-D-xylos-idases hydrolyse xylose monomers from nonreducing endsof xylan oligosaccharides and belong to GH families 3 3943 52 and 54 [53] Studies have indicated production ofseveral xylanases by T bifida and other actinomycetes Tbifida has been found to be producing 120573-14-endoxylan-ases (xyl10A xyl10B and xil11A) xylosidases 120572-L-arabino-furanosidases xyloglucanases 120573-13-glucanases (GH81) and120572-N-arabinofuranosidases (xil43) [36 40] Cellulomonas fimisynthesises extracellular endo- as well as exo-xylanases xylanbinding domain CBM4 120573-mannanase mannosidase andxel74 (xyloglucan specific 120573-14-glucanase) [36 46] Cellu-lomonas flavigena ATCC 482 are known to synthesize anunusual mixture of 19 endoxylanases along with GH10GH11 and GH30 xylanases GH43 (120573-xylosidase) GH51 120572-arabinofuranosidase and 120572-glucuronidase GH26 and GH13mannans and GH16 and GH81 120573-glucanase [46] Strepto-myces flavogriseus has shown production of 120573-14-glucan glu-canohydrolase [54] Xylanase genes GH5 (120573-mannosidase)

GH10 (beta xylanase) GH11 (beta xylanase) CE4 (acetylxy-lan esterase) and GH6 (CBH) and GH9 (CBH) have alsobeen found in Streptomyces sp SirexAA-E (ActE) [48]

33 Lignolytic Enzymes Lignin degradation is mediated bya complex of enzymes containing three principal enzymeslaccases (EC 11032) manganese peroxidases (MnP EC111113) and lignin peroxidases (LiP EC 111114) [55 56]Laccases are the oxidoreductases which degrade polyphenolthe principal recalcitrant component in the lignocellulose [1557] They are extracellular inducible enzymes which employsimple oxygen as an oxidizing agent as well as cofactorThey are multicopper oxidases having four copper atoms intheir active sites taking part in oxygen reduction [58] Lowsubstrate specificity of laccases enables them to degrade widevariety of compounds Manganese and lignin peroxidasesare together known as heme peroxidases containing proto-porphyrin IX as a prosthetic group Lignin peroxidases canspecifically degrade high redox potential compounds and areknown to oxidize phenolic as well as nonphenolic aromaticrings which make up around 90 of the lignin polymerThey require H

(LMCO) four copper atoms are classified in types 1 2 and3 [57 59] The four copper atoms are distributed in threedomains in most of the bacterial and fungal laccases [60]Structural studies in several actinomycetes however haverevealed presence of two Cu-binding domains rather thanthree [61 62] The two-domain structure has been named assmall laccase or small LMCO [59 61] LMCOs in Strepto-myces griseus Streptomyces cyaneus Streptomyces coelicolorStreptomyces ipomoea Streptomyces sviceus Streptomyces spand Thermobifida fusca are active as dimers or trimmers[61 63 64]

5 Diversity of Lignocellulolytic Actinomycetes

51 Cellulolytic Actinomycetes Cellulolytic potential of acti-nomycetes has been explored since inspection of othermicroorganisms for cellulase production Various researchstudies support high cellulose degradation potential ofmicrobes from actinomycetales Table 1 represents the diver-sity of actinomycetes producing cellulase enzymes

52 Hemicellulolytic Actinomycetes Diverse types of actino-mycetes belonging to wide range of habitats and active indifferent environmental conditions are known to producehemicellulolytic enzymes Streptomyces have been found tobe the most abundant hemicellulases producer among acti-nomycetes In a study by Boroujeni et al [74] all of theisolated hemicellulolytic actinomycetes were found to belongto Streptomyces genus Xylanase has been successfully puri-fied from Streptomyces sp E-86 and characterized for itsxylanolytic activity [75] Optimization studies were carriedout for endoxylanase production by Streptomyces sp F2621isolated from Turkey [76] 120573-xylosidase activity of Strepto-myces has been used in saccharification of ball milled wheatstraw [77] A thermostable xylanase was obtained from Strep-tomyces sp QG-11-3 which has shown biobleaching effects ineucalyptus kraft pulp [78] Xylanase has also been producedfrom other strains of Streptomyces sp such as Streptomycessp strain C1-3 [79] Streptomyces sp CD3 [80] Streptomycessp 7b [81] Streptomyces sp PC22 Streptomyces sp 234P-16ISWU-10 Streptomyces sp MDS [82] and Streptomyces sp[83] In Streptomyces rochei and Streptomyces chromofuscusxylanase production has been achieved using treated Papyrusand cotton stalk pulp The obtained xylanase when used forstudying bleaching effects has shown enhanced brightness inthe presence of EDTA [84] Xylanases have also been obtainedfrom Streptomyces albus and Streptomyces hygroscopicus andhave shown successful production of biogas using oil cakeand straw waste [85]

In a study by Ninawe et al [86] three Streptomyces iso-lates that is Streptomyces cyaneus S tendae and S caelestiswere found to be xylanolytic and the enzyme from Strep-tomyces cyaneus was successfully purified followed with its

characterization [87] Streptomyces thermoviolaceus OPC-520 exhibited production of acetyl xylan esterases and 120572-L-arabinofuranosidases enzymes [88] Extracellular xylanaseproduction has also been observed in Streptomyces aureofa-ciens [89] and in Streptomyces coelicolor grown on differentagricultural wastes such as sugarcane bagasse pineappleorange and pomegranate peels [90] Xylanases from Strep-tomyces albus and Streptomyces chromofuscus have indicatedpositive bleaching effects in rice straw pulp [91] Bhosale et al[92] have shown production of 326 IUmL of xylanases fromStreptomyces rameus using sugarcane bagasse along withpeptone and dextrose [92] Studies have indicated productionof cellulase free xylanases from Streptomyces roseiscleroticus[93 94] and Saccharomonospora viridis [95] Improvement inxylanase production has been documented in Streptomycespseudogriseolus subjected to UV mutagenesis [96] Xylanaseproduction has also been seen in Thermomonospora fusca[77 97]Thermomonospora curvataThermomonospora albaMicromonospora Microbispora bispora Nocardia Saccha-romonospora viridis and Thermoactinomyces have shownproduction of 120573-xylosidases acetylesterases and arabinofu-ranosidases [77] Extracellular xylanases have been partiallypurified and characterized in Microbispora siamensis in astudy by Boondaeng et al [98] Xylanase production has alsobeen observed inMicrotetraspora flexuosa [99] Streptomyceschattanoogensis UAH 23 [100] Streptomyces chattanoogensisCECT 3336 [101] Streptomyces violaceoruber [102] Ther-moactinomyces thalophilus [103]Thermomonospora sp [104]Streptomyces thermocyanaeviolaceus [105] and Streptomyceslividans [106] The enzyme from Streptomyces lividans waspurified and characterized by different researchers [107 108]Microbispora sp has been found to be producing hemicellu-lolytic mannanase enzyme [109] whereas other studies haveindicated production of 120573-xylosidases by Streptomyces albo-griseolus S nitrosporeus and Micromonospora melanosporea[110]

53 Lignolytic Actinomycetes Lignolytic activity is exhibitedby diverse range of actinomycetes which play importantrole in biodegradation processes in the environment Searchis in progress for more actinomycetes with high lignolyticpotential using advanced techniques combinedwith conven-tional methods A study by Fernandes et al [111] have usedspecifically designed primers for detection of laccase-likegeneswithin actinomycetes andhas identified gene fragmentsundetectable by known primers which corresponded tosuperfamilies I and K based on laccase and multicopperoxidase engineering database Arias et al [112] have shownproduction of laccase by Streptomyces cyaneus CECT 3335using soya flour Laccase was purified and characterizedand was found to show increase in brightness of eucalyptuskraft pulp in biobleaching studies The enzyme was able tooxidize veratryl alcohol suggesting potential of the strainin industrial applications Veratryl alcohol oxidation andother lignolytic activities have also been demonstrated inStreptomyces viridosporus [113 114]

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

2 Lignocellulose Structure and Uses

Lignocellulose is comprised of three main componentsthat is cellulose hemicellulose and lignin [21] (Figure 1)Cellulose is the high molecular weight linear polymer of D-glucopyranose units linked together by 120573-(lrarr 4)-glycosidicbonds with cellobiose dimer being the repeating unit Thecellulose chains are hydrogen bonded to each other makinga bundle of microfibrils which further aggregate together

to make cellulose fibrils [22] The structure shows variationsfrom amorphous to crystalline regions The cellulose fibrilsare packed in the cell wall in a matrix of hemicelluloses andlignin [23] Hemicelluloses are linear or branched hetero-polysaccharides composed of D-xylose L-arabinose D-gal-actose D-glucose or D-mannose sugars with or withoutdifferent uronic acids and may include xylans mannans glu-cans glucuronoxylans arabinoxylans glucomannans galac-tomannans galactoglucomannans 120573-glucans and xyloglu-cans [10 24] The branching and composition vary amongdifferent plant sources Xylan the polymer of xylose is themost abundant hemicellulosic component [10] Lignin is avery complex polyphenolic heteropolymer primarily madeup of three phenyl propionic alcohol monomers that is p-coumaryl alcohol coniferyl alcohol and sinapyl alcohol [25]

Enzyme Research 3

Celluloses hemicelluloses and lignin are packed closelyin a crisscross network and glued with the help of a variety ofnoncovalent and covalent linkages Lignin acts as a cement-ing agent and provides structural support It also providesimpermeable barrier to the enzymes making whole structurerobust and resistant [22] Cellulose is the most abundantpolymer of plant cell walls (35ndash50) followed with hemicel-lulose (20ndash35) and lignin (10ndash25) [10]

Cellulose is used for many purposes such as in manufac-turing of paper and textile fabric in production of biofuel(from fermentable sugar glucose) as inert packing and insu-lating material and in food and drugs as base and stabilizer[26] Hemicelluloses are utilized in a range of applicationsBiodegradability and nontoxicity of hemicelluloses enable itto be used as dietary fibre [27] and as edible coating overfoodstuffs for their stabilization Mannans have cholesterollowering properties [28] Xyloglucans and 120573-glucans are usedin ice-creams and other foods due to their gelling stabilizingand thickening effects Adhesive properties are used in papermaking Hemicelluloses are rich source of xylose sugarswhich are fermented to ethanol fuel [29] Characteristics oflignin also make it an important component used in the pro-duction of a wide range of value added products [30] Lignincan be used as a source of activated carbon and phenol usefulin the synthesis of wide array of chemicals [31] and to producebiocomposites [32] or polymers [33] which can replace plasticbased products either partially or completely It can be usedas binder in small scale processes and as filler in place ofoil based carbon fibres Biosorption properties of lignin [34]are also foreseen as a potent application Furthermore ligninis a rich source of energy [35] Thus lignocellulose is arepertoire of industrially useful components But the struc-tural characteristics of the cell wall or lignocellulose are suchthat the extraction of individual component to homogeneityand purity is a difficult task requiring specific chemical orbiological procedures Also many applications are based ondegradation products of the cellulose hemicellulose or ligninmaking hydrolysis an essential requirement Hydrolysis canbe mediated both chemically and enzymatically Chemicalmethods involve use of expensive chemicals harsh condi-tions and have certain other limitations Enzymatic methodsare therefore preferred and lignocellulolytic enzymes playvery important role in these applications Presently biomassutilization is executed through biorefinery which aims atsignificant utilization of all components generating leastpossible amount of waste When one constituent of biomassis utilized others are simultaneously used for production ofvaluable products During biofuel production sugars fromhemicellulose and cellulose components are used in ethanolformation and lignin residue left is used for power generationor in other uses of lignin Lignocellulases perform importantfunctions in biorefinery processes also

3 Lignocellulolytic EnzymeSystems in Actinomycetes

31 Cellulases Cellulolytic enzymes are a group of glycosylhydrolases classified into different families depending on

their sequence homologies The mechanisms of action andsubstrate specificities vary among different cellulases butthey are generally divided into exoglucanases (EC 32174)endoglucanases (EC 3214) cellobiohydrolases (EC 32191)and 120573-glucosidases (EC 32121) [36 37] Exoglucanasesact on reducing or nonreducing ends of cellulose chainsreleasing glucose units whereas endoglucanases hydrolyse120573-14-glycosidic bonds randomly inside the cellulose chainsreleasing dextrans of variable lengths [38] Cellobiohydro-lases cleave glycosidic bonds at nonreducing ends andrelease cellobiose units [39] These enzymes are particularlyimportant in hydrolysing crystalline cellulose because oftheir processivity [36] 120573-glucosidases enzymes take part inhydrolysis of cellobiose units to monomeric glucose [38]Complete hydrolysis of cellulose involves synergistic effect ofall these enzymes showing synergy between endoglucanasesand exoglucanases (endo-exo synergy) exoglucanases actingon the reducing and nonreducing ends (exo-exo synergy)between cellobiohydrolases and 120573-glucosidases and betweencatalytic and carbohydrate binding domains [39] Figure 2shows schematic presentation of enzymatic hydrolysis of cel-lulose polymer

Microbial cellulase systems are either complexed ornoncomplexed [39] Complexed systems known as cellulo-somes are characteristics of anaerobic bacteria consisting ofmultienzyme complex protuberances from cell surface stabi-lized by dockerin and adhesion proteins In aerobic bacteriaincluding most of the actinomycetes cellulases are noncom-plexed or free and are secreted extracellularly using specificsecretion pathways

Among cellulase producing actinomycetes CellulomonasfimiMicrobispora bispora andThermobifida fusca have beenstudied extensively [6 39] Thermobifida fusca is a ther-mophilic spore forming actinomycete [6] The genome ofT fusca consists of 36 billion bp in a single circular chro-mosome with 3117 coding sequences and has 675 G+Ccontent which stabilizes DNA in extreme temperature condi-tions [40] The genome encodes for 36 glycoside hydrolasesdistributed in 22 GH (glycoside hydrolases) families [40]Cellulase system of T fusca is comprised of six extracellularcellulases (4 endocellulases and 2 exocellulases) and oneintracellular 120573-glucosidase [6 40ndash42] Each enzyme has aseparate catalytic and carbohydrate binding domain bothlinked together with a linker peptide [36 41] Carbohydratebinding domains in all six cellulases belong to the samefamily that is 2CBD [41] The catalytic domains howeverare different in all enzymes belonging to different familieswith Cel5A and Cel5B from GH family 5 Cel6A and Cel6Bfrom GH family 6 Cel9A and Cel9B from GH family 9 andCel48A from family 48 [43] Cel5A Cel5B Cel6A and Cel9Bare endocellulases and do not show processivity [36 40 41]Cel6B and Cel48A are processive exocellulases which act atnonreducing and reducing ends respectively Cel9A is a novelprocessive cellulase with both exo- and endocellulase actionsstarting exohydrolysis from the nonreducing end [36] Theposition of CBD varies in different cellulases which is N-terminus in Cel5A Cel6B and Cel48A and C-terminus inCel6A Cel9A and Cel9B [41] Sequence studies of catalyticdomains have revealed less than 31 similarity between

cellulases from taxonomically similar as well as dissimilarmicrobes which indicates development of cellulase systemas a result of horizontal gene transfer compared to the geneduplication [44] The three-dimensional structure of Cel6Ashows 120572-120573 barrel with a deep active site cleft formed by oneshorter and one turned loop consisting of four conservedAsp residues [42 45] Active site of GH48 is also in a cleft[42] Structural characteristics of exocellulases allow them tobind processively whereas open active sites of endocellulasesenable them to bind cellulose internally at random sites [42]Structural elucidation of Cel9A has shown that it gives activ-ity between exo- and endocellulases because its weak bindingdomain 3c CBD is aligned with the active site in the catalyticdomain allowing processive hydrolysis by the enzyme [42]Tfusca also produces cellulose and chitin binding proteins E7and E8 the CBM33 proteins which improve cellulose hydrol-ysis mediated through exoglucanases [36 40 42] Cellulasesfrom T bifida have also been found showing synergism withendocellulases and Trichoderma reesei CBHI [6]

Cellulomonas fimi is a facultative anaerobe but it does notconsist of cellulosomes of cellulolytic anaerobes rather it pro-duces free cellulases [46] Similarly facultatively anaerobicCellulomonas flavigena also secrets free cellulases [46] Bothcarry out efficient hydrolysis of celluloses and hemicelluloses

The cellulase enzyme systems in Cellulomonas fimi also con-sist of six cellulases [39] that is three endocellulases (CenACenB and CenD) two exocellulases (CbhA and CbhB) anda processive endocellulase CenC [41 46] All these enzymeshave activities similar to that inT bifida with same families ofCBDs (2CBD) and catalytic domains but different sequences[41 47] These cellulases are primarily secreted by sec depen-dent pathway [46] and therefore do not require intracellularfolding or cofactors for their activity InC fimiATCC484 andC flavigena ATCC 482 another enzyme GH94 (cellobiosephosphorylase) has also been discovered [46] Microbisporabispora also shows synthesis of six different cellulases show-ing exo-exo and endo-exo synergism [6] Genomic studiesof Streptomyces sp SirexAA-E (ActE) isolated from pine-boring woodwasp Sirex noctilio have also shown genes forGH48 (CBH activity) GH74 (endocellulase) and CDB33[48] Streptomyces coelicolor consisted of 221 carbohydrateactive enzymes (CAZy) or 154 glycosyl hydrolases (GHs)encoded within 86 billion bp long genome [48]

The expression of cellulolytic genes in T bifida is inducedby cellobiose whereas easily utilizable sugar glucose showscatabolite repression as in most of the other cellulolyticmicrobes [49]The regulation of cellulolytic genes ismediatedby the CelR repressor which binds to a 9ndash14 bp palindrome

(51015840-TGGGAGCGCTCCCA-31015840) in region 51015840-upstream of thecellulase genes in the absence of cellobiose or cellulose [50]During induction cellulose is hydrolysed to cellobiose byconstitutive cellulases Cellobiose binds to CelR releasing itfrom the promoter allowing transcription of the downstreamgenes [47] In addition to the presence of glucose cellulasegenes expression is also regulated by cAMP levels

The extracellular cellulases are secreted by actinomycetesusing either one or both of the common bacterial systemsfor secretion of extracellular proteins that is sec generalsecretion system and sec independent twin-arginine translo-cation (TAT) systems The general Secretion route catalysestransmembrane translocation of proteins in their unfoldedconformation whereas Twin-arginine (TAT) system translo-cates secretory proteins in their native folded state InT bifidaboth of these systems were discovered whereas S coelicolormainly utilizes TAT systems for protein export [40]

32 Hemicellulases Hemicellulases are generally synthesisedalong with cellulases [36 39] Xylan and mannan are mostabundant components of hemicelluloses Complete hydroly-sis of xylan involves an enzyme system consisting of endo-14-120573-xylanases (EC 3218) 120573-D-xylosidases (EC 32137)120572-L-arabinofuranosidases (EC 32155) 120572-glucuronidases(EC 321139) acetyl xylan esterases (EC 31172) and fer-uliccoumaric acid esterases (EC 31173) Mannan is hydrol-ysed primarily by synergistic action of mannanases (EC32178) 120573-mannosidases (EC 32125) and 120572-galactosidases(EC 32122) [36 51] Mannanases hydrolyze 120573-14-glycosidicbonds internally 120573-mannosidase cleave 120573-14 linked man-nose from nonreducing ends and 120572-galactosidase removesterminal D-galactosyl residues linked by 120572-16 linkages [52]Degradation of mannan and xylan also enhances cellulosehydrolysis as they are known to inhibit cellulase activities[36]

Most of the hemicellulases belong to glycosyl hydrolasesfamilies however some enzymes involved in hemicellulosehydrolysis belong to glycosyltransferases (EC 241x) [39]Xylanases hydrolysing internal 120573-14-glycosidic bonds areclassified into GH families 5 7 8 10 11 and 43 120573-D-xylos-idases hydrolyse xylose monomers from nonreducing endsof xylan oligosaccharides and belong to GH families 3 3943 52 and 54 [53] Studies have indicated production ofseveral xylanases by T bifida and other actinomycetes Tbifida has been found to be producing 120573-14-endoxylan-ases (xyl10A xyl10B and xil11A) xylosidases 120572-L-arabino-furanosidases xyloglucanases 120573-13-glucanases (GH81) and120572-N-arabinofuranosidases (xil43) [36 40] Cellulomonas fimisynthesises extracellular endo- as well as exo-xylanases xylanbinding domain CBM4 120573-mannanase mannosidase andxel74 (xyloglucan specific 120573-14-glucanase) [36 46] Cellu-lomonas flavigena ATCC 482 are known to synthesize anunusual mixture of 19 endoxylanases along with GH10GH11 and GH30 xylanases GH43 (120573-xylosidase) GH51 120572-arabinofuranosidase and 120572-glucuronidase GH26 and GH13mannans and GH16 and GH81 120573-glucanase [46] Strepto-myces flavogriseus has shown production of 120573-14-glucan glu-canohydrolase [54] Xylanase genes GH5 (120573-mannosidase)

GH10 (beta xylanase) GH11 (beta xylanase) CE4 (acetylxy-lan esterase) and GH6 (CBH) and GH9 (CBH) have alsobeen found in Streptomyces sp SirexAA-E (ActE) [48]

33 Lignolytic Enzymes Lignin degradation is mediated bya complex of enzymes containing three principal enzymeslaccases (EC 11032) manganese peroxidases (MnP EC111113) and lignin peroxidases (LiP EC 111114) [55 56]Laccases are the oxidoreductases which degrade polyphenolthe principal recalcitrant component in the lignocellulose [1557] They are extracellular inducible enzymes which employsimple oxygen as an oxidizing agent as well as cofactorThey are multicopper oxidases having four copper atoms intheir active sites taking part in oxygen reduction [58] Lowsubstrate specificity of laccases enables them to degrade widevariety of compounds Manganese and lignin peroxidasesare together known as heme peroxidases containing proto-porphyrin IX as a prosthetic group Lignin peroxidases canspecifically degrade high redox potential compounds and areknown to oxidize phenolic as well as nonphenolic aromaticrings which make up around 90 of the lignin polymerThey require H

attractive substrate for LiP which oxidises other substratesby acting as the redox mediator for indirect oxidation Man-ganese peroxidases are low redox potential heme peroxidasesrequiring H

dependent or versatile peroxidases [56 58]Laccases or Laccase-likemulticopper oxidases containing

(LMCO) four copper atoms are classified in types 1 2 and3 [57 59] The four copper atoms are distributed in threedomains in most of the bacterial and fungal laccases [60]Structural studies in several actinomycetes however haverevealed presence of two Cu-binding domains rather thanthree [61 62] The two-domain structure has been named assmall laccase or small LMCO [59 61] LMCOs in Strepto-myces griseus Streptomyces cyaneus Streptomyces coelicolorStreptomyces ipomoea Streptomyces sviceus Streptomyces spand Thermobifida fusca are active as dimers or trimmers[61 63 64]

4 Genetic Engineering

The genes from several lignocellulolytic actinomycetes havebeen successfully cloned to show heterologous expression indifferent microbes GH1 and GH3 enzymes of C fimi ATCC484 expressed in E coli have shown efficient hydrolysis ofcelluloses and xylanases [65] CelStrep gene from cellulolyticStreptomyces sp G12 cloned and expressed in E coli wasfound to belong to GH12 family and catalysed hydrolysis ofcarboxymethylcellulose following aMichaelis-Menten kinet-ics with a 119870

well characterized in Streptomyces lividans [69] Xylanasegene xylBS27 belonging to GH11 from Streptomyces sp S27has been successfully cloned and expressed in Pichia pastorishydrolysing xylan to xylobiose [70] Similarly expression oflaccase gene from Streptomyces coelicolor (SLAC) in Strepto-myces lividans produced large amount of high purity laccase(350mg Lminus1) [71] The gene for a thermostable laccase fromStreptomyces lavendulae REN-7 was successfully cloned andexpressed in E coli [72] Cloning of a lignin peroxidase fromStreptomyces viridosporus T7A into Streptomyces lividansTK64 has resulted in better lignocellulose degradation bygenetically engineered S lividans compared to S lividansTK64 [73] Thus genetic engineering techniques can be andare being used for constructing industrially valuable strainswith potent applications based on actinomycetes lignocel-lulolytic enzymes

5 Diversity of Lignocellulolytic Actinomycetes

51 Cellulolytic Actinomycetes Cellulolytic potential of acti-nomycetes has been explored since inspection of othermicroorganisms for cellulase production Various researchstudies support high cellulose degradation potential ofmicrobes from actinomycetales Table 1 represents the diver-sity of actinomycetes producing cellulase enzymes

52 Hemicellulolytic Actinomycetes Diverse types of actino-mycetes belonging to wide range of habitats and active indifferent environmental conditions are known to producehemicellulolytic enzymes Streptomyces have been found tobe the most abundant hemicellulases producer among acti-nomycetes In a study by Boroujeni et al [74] all of theisolated hemicellulolytic actinomycetes were found to belongto Streptomyces genus Xylanase has been successfully puri-fied from Streptomyces sp E-86 and characterized for itsxylanolytic activity [75] Optimization studies were carriedout for endoxylanase production by Streptomyces sp F2621isolated from Turkey [76] 120573-xylosidase activity of Strepto-myces has been used in saccharification of ball milled wheatstraw [77] A thermostable xylanase was obtained from Strep-tomyces sp QG-11-3 which has shown biobleaching effects ineucalyptus kraft pulp [78] Xylanase has also been producedfrom other strains of Streptomyces sp such as Streptomycessp strain C1-3 [79] Streptomyces sp CD3 [80] Streptomycessp 7b [81] Streptomyces sp PC22 Streptomyces sp 234P-16ISWU-10 Streptomyces sp MDS [82] and Streptomyces sp[83] In Streptomyces rochei and Streptomyces chromofuscusxylanase production has been achieved using treated Papyrusand cotton stalk pulp The obtained xylanase when used forstudying bleaching effects has shown enhanced brightness inthe presence of EDTA [84] Xylanases have also been obtainedfrom Streptomyces albus and Streptomyces hygroscopicus andhave shown successful production of biogas using oil cakeand straw waste [85]

In a study by Ninawe et al [86] three Streptomyces iso-lates that is Streptomyces cyaneus S tendae and S caelestiswere found to be xylanolytic and the enzyme from Strep-tomyces cyaneus was successfully purified followed with its

characterization [87] Streptomyces thermoviolaceus OPC-520 exhibited production of acetyl xylan esterases and 120572-L-arabinofuranosidases enzymes [88] Extracellular xylanaseproduction has also been observed in Streptomyces aureofa-ciens [89] and in Streptomyces coelicolor grown on differentagricultural wastes such as sugarcane bagasse pineappleorange and pomegranate peels [90] Xylanases from Strep-tomyces albus and Streptomyces chromofuscus have indicatedpositive bleaching effects in rice straw pulp [91] Bhosale et al[92] have shown production of 326 IUmL of xylanases fromStreptomyces rameus using sugarcane bagasse along withpeptone and dextrose [92] Studies have indicated productionof cellulase free xylanases from Streptomyces roseiscleroticus[93 94] and Saccharomonospora viridis [95] Improvement inxylanase production has been documented in Streptomycespseudogriseolus subjected to UV mutagenesis [96] Xylanaseproduction has also been seen in Thermomonospora fusca[77 97]Thermomonospora curvataThermomonospora albaMicromonospora Microbispora bispora Nocardia Saccha-romonospora viridis and Thermoactinomyces have shownproduction of 120573-xylosidases acetylesterases and arabinofu-ranosidases [77] Extracellular xylanases have been partiallypurified and characterized in Microbispora siamensis in astudy by Boondaeng et al [98] Xylanase production has alsobeen observed inMicrotetraspora flexuosa [99] Streptomyceschattanoogensis UAH 23 [100] Streptomyces chattanoogensisCECT 3336 [101] Streptomyces violaceoruber [102] Ther-moactinomyces thalophilus [103]Thermomonospora sp [104]Streptomyces thermocyanaeviolaceus [105] and Streptomyceslividans [106] The enzyme from Streptomyces lividans waspurified and characterized by different researchers [107 108]Microbispora sp has been found to be producing hemicellu-lolytic mannanase enzyme [109] whereas other studies haveindicated production of 120573-xylosidases by Streptomyces albo-griseolus S nitrosporeus and Micromonospora melanosporea[110]

53 Lignolytic Actinomycetes Lignolytic activity is exhibitedby diverse range of actinomycetes which play importantrole in biodegradation processes in the environment Searchis in progress for more actinomycetes with high lignolyticpotential using advanced techniques combinedwith conven-tional methods A study by Fernandes et al [111] have usedspecifically designed primers for detection of laccase-likegeneswithin actinomycetes andhas identified gene fragmentsundetectable by known primers which corresponded tosuperfamilies I and K based on laccase and multicopperoxidase engineering database Arias et al [112] have shownproduction of laccase by Streptomyces cyaneus CECT 3335using soya flour Laccase was purified and characterizedand was found to show increase in brightness of eucalyptuskraft pulp in biobleaching studies The enzyme was able tooxidize veratryl alcohol suggesting potential of the strainin industrial applications Veratryl alcohol oxidation andother lignolytic activities have also been demonstrated inStreptomyces viridosporus [113 114]

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

Celluloses hemicelluloses and lignin are packed closelyin a crisscross network and glued with the help of a variety ofnoncovalent and covalent linkages Lignin acts as a cement-ing agent and provides structural support It also providesimpermeable barrier to the enzymes making whole structurerobust and resistant [22] Cellulose is the most abundantpolymer of plant cell walls (35ndash50) followed with hemicel-lulose (20ndash35) and lignin (10ndash25) [10]

Cellulose is used for many purposes such as in manufac-turing of paper and textile fabric in production of biofuel(from fermentable sugar glucose) as inert packing and insu-lating material and in food and drugs as base and stabilizer[26] Hemicelluloses are utilized in a range of applicationsBiodegradability and nontoxicity of hemicelluloses enable itto be used as dietary fibre [27] and as edible coating overfoodstuffs for their stabilization Mannans have cholesterollowering properties [28] Xyloglucans and 120573-glucans are usedin ice-creams and other foods due to their gelling stabilizingand thickening effects Adhesive properties are used in papermaking Hemicelluloses are rich source of xylose sugarswhich are fermented to ethanol fuel [29] Characteristics oflignin also make it an important component used in the pro-duction of a wide range of value added products [30] Lignincan be used as a source of activated carbon and phenol usefulin the synthesis of wide array of chemicals [31] and to producebiocomposites [32] or polymers [33] which can replace plasticbased products either partially or completely It can be usedas binder in small scale processes and as filler in place ofoil based carbon fibres Biosorption properties of lignin [34]are also foreseen as a potent application Furthermore ligninis a rich source of energy [35] Thus lignocellulose is arepertoire of industrially useful components But the struc-tural characteristics of the cell wall or lignocellulose are suchthat the extraction of individual component to homogeneityand purity is a difficult task requiring specific chemical orbiological procedures Also many applications are based ondegradation products of the cellulose hemicellulose or ligninmaking hydrolysis an essential requirement Hydrolysis canbe mediated both chemically and enzymatically Chemicalmethods involve use of expensive chemicals harsh condi-tions and have certain other limitations Enzymatic methodsare therefore preferred and lignocellulolytic enzymes playvery important role in these applications Presently biomassutilization is executed through biorefinery which aims atsignificant utilization of all components generating leastpossible amount of waste When one constituent of biomassis utilized others are simultaneously used for production ofvaluable products During biofuel production sugars fromhemicellulose and cellulose components are used in ethanolformation and lignin residue left is used for power generationor in other uses of lignin Lignocellulases perform importantfunctions in biorefinery processes also

3 Lignocellulolytic EnzymeSystems in Actinomycetes

31 Cellulases Cellulolytic enzymes are a group of glycosylhydrolases classified into different families depending on

their sequence homologies The mechanisms of action andsubstrate specificities vary among different cellulases butthey are generally divided into exoglucanases (EC 32174)endoglucanases (EC 3214) cellobiohydrolases (EC 32191)and 120573-glucosidases (EC 32121) [36 37] Exoglucanasesact on reducing or nonreducing ends of cellulose chainsreleasing glucose units whereas endoglucanases hydrolyse120573-14-glycosidic bonds randomly inside the cellulose chainsreleasing dextrans of variable lengths [38] Cellobiohydro-lases cleave glycosidic bonds at nonreducing ends andrelease cellobiose units [39] These enzymes are particularlyimportant in hydrolysing crystalline cellulose because oftheir processivity [36] 120573-glucosidases enzymes take part inhydrolysis of cellobiose units to monomeric glucose [38]Complete hydrolysis of cellulose involves synergistic effect ofall these enzymes showing synergy between endoglucanasesand exoglucanases (endo-exo synergy) exoglucanases actingon the reducing and nonreducing ends (exo-exo synergy)between cellobiohydrolases and 120573-glucosidases and betweencatalytic and carbohydrate binding domains [39] Figure 2shows schematic presentation of enzymatic hydrolysis of cel-lulose polymer

Microbial cellulase systems are either complexed ornoncomplexed [39] Complexed systems known as cellulo-somes are characteristics of anaerobic bacteria consisting ofmultienzyme complex protuberances from cell surface stabi-lized by dockerin and adhesion proteins In aerobic bacteriaincluding most of the actinomycetes cellulases are noncom-plexed or free and are secreted extracellularly using specificsecretion pathways

Among cellulase producing actinomycetes CellulomonasfimiMicrobispora bispora andThermobifida fusca have beenstudied extensively [6 39] Thermobifida fusca is a ther-mophilic spore forming actinomycete [6] The genome ofT fusca consists of 36 billion bp in a single circular chro-mosome with 3117 coding sequences and has 675 G+Ccontent which stabilizes DNA in extreme temperature condi-tions [40] The genome encodes for 36 glycoside hydrolasesdistributed in 22 GH (glycoside hydrolases) families [40]Cellulase system of T fusca is comprised of six extracellularcellulases (4 endocellulases and 2 exocellulases) and oneintracellular 120573-glucosidase [6 40ndash42] Each enzyme has aseparate catalytic and carbohydrate binding domain bothlinked together with a linker peptide [36 41] Carbohydratebinding domains in all six cellulases belong to the samefamily that is 2CBD [41] The catalytic domains howeverare different in all enzymes belonging to different familieswith Cel5A and Cel5B from GH family 5 Cel6A and Cel6Bfrom GH family 6 Cel9A and Cel9B from GH family 9 andCel48A from family 48 [43] Cel5A Cel5B Cel6A and Cel9Bare endocellulases and do not show processivity [36 40 41]Cel6B and Cel48A are processive exocellulases which act atnonreducing and reducing ends respectively Cel9A is a novelprocessive cellulase with both exo- and endocellulase actionsstarting exohydrolysis from the nonreducing end [36] Theposition of CBD varies in different cellulases which is N-terminus in Cel5A Cel6B and Cel48A and C-terminus inCel6A Cel9A and Cel9B [41] Sequence studies of catalyticdomains have revealed less than 31 similarity between

cellulases from taxonomically similar as well as dissimilarmicrobes which indicates development of cellulase systemas a result of horizontal gene transfer compared to the geneduplication [44] The three-dimensional structure of Cel6Ashows 120572-120573 barrel with a deep active site cleft formed by oneshorter and one turned loop consisting of four conservedAsp residues [42 45] Active site of GH48 is also in a cleft[42] Structural characteristics of exocellulases allow them tobind processively whereas open active sites of endocellulasesenable them to bind cellulose internally at random sites [42]Structural elucidation of Cel9A has shown that it gives activ-ity between exo- and endocellulases because its weak bindingdomain 3c CBD is aligned with the active site in the catalyticdomain allowing processive hydrolysis by the enzyme [42]Tfusca also produces cellulose and chitin binding proteins E7and E8 the CBM33 proteins which improve cellulose hydrol-ysis mediated through exoglucanases [36 40 42] Cellulasesfrom T bifida have also been found showing synergism withendocellulases and Trichoderma reesei CBHI [6]

Cellulomonas fimi is a facultative anaerobe but it does notconsist of cellulosomes of cellulolytic anaerobes rather it pro-duces free cellulases [46] Similarly facultatively anaerobicCellulomonas flavigena also secrets free cellulases [46] Bothcarry out efficient hydrolysis of celluloses and hemicelluloses

The cellulase enzyme systems in Cellulomonas fimi also con-sist of six cellulases [39] that is three endocellulases (CenACenB and CenD) two exocellulases (CbhA and CbhB) anda processive endocellulase CenC [41 46] All these enzymeshave activities similar to that inT bifida with same families ofCBDs (2CBD) and catalytic domains but different sequences[41 47] These cellulases are primarily secreted by sec depen-dent pathway [46] and therefore do not require intracellularfolding or cofactors for their activity InC fimiATCC484 andC flavigena ATCC 482 another enzyme GH94 (cellobiosephosphorylase) has also been discovered [46] Microbisporabispora also shows synthesis of six different cellulases show-ing exo-exo and endo-exo synergism [6] Genomic studiesof Streptomyces sp SirexAA-E (ActE) isolated from pine-boring woodwasp Sirex noctilio have also shown genes forGH48 (CBH activity) GH74 (endocellulase) and CDB33[48] Streptomyces coelicolor consisted of 221 carbohydrateactive enzymes (CAZy) or 154 glycosyl hydrolases (GHs)encoded within 86 billion bp long genome [48]

The expression of cellulolytic genes in T bifida is inducedby cellobiose whereas easily utilizable sugar glucose showscatabolite repression as in most of the other cellulolyticmicrobes [49]The regulation of cellulolytic genes ismediatedby the CelR repressor which binds to a 9ndash14 bp palindrome

(51015840-TGGGAGCGCTCCCA-31015840) in region 51015840-upstream of thecellulase genes in the absence of cellobiose or cellulose [50]During induction cellulose is hydrolysed to cellobiose byconstitutive cellulases Cellobiose binds to CelR releasing itfrom the promoter allowing transcription of the downstreamgenes [47] In addition to the presence of glucose cellulasegenes expression is also regulated by cAMP levels

The extracellular cellulases are secreted by actinomycetesusing either one or both of the common bacterial systemsfor secretion of extracellular proteins that is sec generalsecretion system and sec independent twin-arginine translo-cation (TAT) systems The general Secretion route catalysestransmembrane translocation of proteins in their unfoldedconformation whereas Twin-arginine (TAT) system translo-cates secretory proteins in their native folded state InT bifidaboth of these systems were discovered whereas S coelicolormainly utilizes TAT systems for protein export [40]

32 Hemicellulases Hemicellulases are generally synthesisedalong with cellulases [36 39] Xylan and mannan are mostabundant components of hemicelluloses Complete hydroly-sis of xylan involves an enzyme system consisting of endo-14-120573-xylanases (EC 3218) 120573-D-xylosidases (EC 32137)120572-L-arabinofuranosidases (EC 32155) 120572-glucuronidases(EC 321139) acetyl xylan esterases (EC 31172) and fer-uliccoumaric acid esterases (EC 31173) Mannan is hydrol-ysed primarily by synergistic action of mannanases (EC32178) 120573-mannosidases (EC 32125) and 120572-galactosidases(EC 32122) [36 51] Mannanases hydrolyze 120573-14-glycosidicbonds internally 120573-mannosidase cleave 120573-14 linked man-nose from nonreducing ends and 120572-galactosidase removesterminal D-galactosyl residues linked by 120572-16 linkages [52]Degradation of mannan and xylan also enhances cellulosehydrolysis as they are known to inhibit cellulase activities[36]

Most of the hemicellulases belong to glycosyl hydrolasesfamilies however some enzymes involved in hemicellulosehydrolysis belong to glycosyltransferases (EC 241x) [39]Xylanases hydrolysing internal 120573-14-glycosidic bonds areclassified into GH families 5 7 8 10 11 and 43 120573-D-xylos-idases hydrolyse xylose monomers from nonreducing endsof xylan oligosaccharides and belong to GH families 3 3943 52 and 54 [53] Studies have indicated production ofseveral xylanases by T bifida and other actinomycetes Tbifida has been found to be producing 120573-14-endoxylan-ases (xyl10A xyl10B and xil11A) xylosidases 120572-L-arabino-furanosidases xyloglucanases 120573-13-glucanases (GH81) and120572-N-arabinofuranosidases (xil43) [36 40] Cellulomonas fimisynthesises extracellular endo- as well as exo-xylanases xylanbinding domain CBM4 120573-mannanase mannosidase andxel74 (xyloglucan specific 120573-14-glucanase) [36 46] Cellu-lomonas flavigena ATCC 482 are known to synthesize anunusual mixture of 19 endoxylanases along with GH10GH11 and GH30 xylanases GH43 (120573-xylosidase) GH51 120572-arabinofuranosidase and 120572-glucuronidase GH26 and GH13mannans and GH16 and GH81 120573-glucanase [46] Strepto-myces flavogriseus has shown production of 120573-14-glucan glu-canohydrolase [54] Xylanase genes GH5 (120573-mannosidase)

GH10 (beta xylanase) GH11 (beta xylanase) CE4 (acetylxy-lan esterase) and GH6 (CBH) and GH9 (CBH) have alsobeen found in Streptomyces sp SirexAA-E (ActE) [48]

33 Lignolytic Enzymes Lignin degradation is mediated bya complex of enzymes containing three principal enzymeslaccases (EC 11032) manganese peroxidases (MnP EC111113) and lignin peroxidases (LiP EC 111114) [55 56]Laccases are the oxidoreductases which degrade polyphenolthe principal recalcitrant component in the lignocellulose [1557] They are extracellular inducible enzymes which employsimple oxygen as an oxidizing agent as well as cofactorThey are multicopper oxidases having four copper atoms intheir active sites taking part in oxygen reduction [58] Lowsubstrate specificity of laccases enables them to degrade widevariety of compounds Manganese and lignin peroxidasesare together known as heme peroxidases containing proto-porphyrin IX as a prosthetic group Lignin peroxidases canspecifically degrade high redox potential compounds and areknown to oxidize phenolic as well as nonphenolic aromaticrings which make up around 90 of the lignin polymerThey require H

2O2for their activity Veratryl alcohol is an

attractive substrate for LiP which oxidises other substratesby acting as the redox mediator for indirect oxidation Man-ganese peroxidases are low redox potential heme peroxidasesrequiring H

dependent or versatile peroxidases [56 58]Laccases or Laccase-likemulticopper oxidases containing

(LMCO) four copper atoms are classified in types 1 2 and3 [57 59] The four copper atoms are distributed in threedomains in most of the bacterial and fungal laccases [60]Structural studies in several actinomycetes however haverevealed presence of two Cu-binding domains rather thanthree [61 62] The two-domain structure has been named assmall laccase or small LMCO [59 61] LMCOs in Strepto-myces griseus Streptomyces cyaneus Streptomyces coelicolorStreptomyces ipomoea Streptomyces sviceus Streptomyces spand Thermobifida fusca are active as dimers or trimmers[61 63 64]

5 Diversity of Lignocellulolytic Actinomycetes

51 Cellulolytic Actinomycetes Cellulolytic potential of acti-nomycetes has been explored since inspection of othermicroorganisms for cellulase production Various researchstudies support high cellulose degradation potential ofmicrobes from actinomycetales Table 1 represents the diver-sity of actinomycetes producing cellulase enzymes

52 Hemicellulolytic Actinomycetes Diverse types of actino-mycetes belonging to wide range of habitats and active indifferent environmental conditions are known to producehemicellulolytic enzymes Streptomyces have been found tobe the most abundant hemicellulases producer among acti-nomycetes In a study by Boroujeni et al [74] all of theisolated hemicellulolytic actinomycetes were found to belongto Streptomyces genus Xylanase has been successfully puri-fied from Streptomyces sp E-86 and characterized for itsxylanolytic activity [75] Optimization studies were carriedout for endoxylanase production by Streptomyces sp F2621isolated from Turkey [76] 120573-xylosidase activity of Strepto-myces has been used in saccharification of ball milled wheatstraw [77] A thermostable xylanase was obtained from Strep-tomyces sp QG-11-3 which has shown biobleaching effects ineucalyptus kraft pulp [78] Xylanase has also been producedfrom other strains of Streptomyces sp such as Streptomycessp strain C1-3 [79] Streptomyces sp CD3 [80] Streptomycessp 7b [81] Streptomyces sp PC22 Streptomyces sp 234P-16ISWU-10 Streptomyces sp MDS [82] and Streptomyces sp[83] In Streptomyces rochei and Streptomyces chromofuscusxylanase production has been achieved using treated Papyrusand cotton stalk pulp The obtained xylanase when used forstudying bleaching effects has shown enhanced brightness inthe presence of EDTA [84] Xylanases have also been obtainedfrom Streptomyces albus and Streptomyces hygroscopicus andhave shown successful production of biogas using oil cakeand straw waste [85]

In a study by Ninawe et al [86] three Streptomyces iso-lates that is Streptomyces cyaneus S tendae and S caelestiswere found to be xylanolytic and the enzyme from Strep-tomyces cyaneus was successfully purified followed with its

characterization [87] Streptomyces thermoviolaceus OPC-520 exhibited production of acetyl xylan esterases and 120572-L-arabinofuranosidases enzymes [88] Extracellular xylanaseproduction has also been observed in Streptomyces aureofa-ciens [89] and in Streptomyces coelicolor grown on differentagricultural wastes such as sugarcane bagasse pineappleorange and pomegranate peels [90] Xylanases from Strep-tomyces albus and Streptomyces chromofuscus have indicatedpositive bleaching effects in rice straw pulp [91] Bhosale et al[92] have shown production of 326 IUmL of xylanases fromStreptomyces rameus using sugarcane bagasse along withpeptone and dextrose [92] Studies have indicated productionof cellulase free xylanases from Streptomyces roseiscleroticus[93 94] and Saccharomonospora viridis [95] Improvement inxylanase production has been documented in Streptomycespseudogriseolus subjected to UV mutagenesis [96] Xylanaseproduction has also been seen in Thermomonospora fusca[77 97]Thermomonospora curvataThermomonospora albaMicromonospora Microbispora bispora Nocardia Saccha-romonospora viridis and Thermoactinomyces have shownproduction of 120573-xylosidases acetylesterases and arabinofu-ranosidases [77] Extracellular xylanases have been partiallypurified and characterized in Microbispora siamensis in astudy by Boondaeng et al [98] Xylanase production has alsobeen observed inMicrotetraspora flexuosa [99] Streptomyceschattanoogensis UAH 23 [100] Streptomyces chattanoogensisCECT 3336 [101] Streptomyces violaceoruber [102] Ther-moactinomyces thalophilus [103]Thermomonospora sp [104]Streptomyces thermocyanaeviolaceus [105] and Streptomyceslividans [106] The enzyme from Streptomyces lividans waspurified and characterized by different researchers [107 108]Microbispora sp has been found to be producing hemicellu-lolytic mannanase enzyme [109] whereas other studies haveindicated production of 120573-xylosidases by Streptomyces albo-griseolus S nitrosporeus and Micromonospora melanosporea[110]

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

cellulases from taxonomically similar as well as dissimilarmicrobes which indicates development of cellulase systemas a result of horizontal gene transfer compared to the geneduplication [44] The three-dimensional structure of Cel6Ashows 120572-120573 barrel with a deep active site cleft formed by oneshorter and one turned loop consisting of four conservedAsp residues [42 45] Active site of GH48 is also in a cleft[42] Structural characteristics of exocellulases allow them tobind processively whereas open active sites of endocellulasesenable them to bind cellulose internally at random sites [42]Structural elucidation of Cel9A has shown that it gives activ-ity between exo- and endocellulases because its weak bindingdomain 3c CBD is aligned with the active site in the catalyticdomain allowing processive hydrolysis by the enzyme [42]Tfusca also produces cellulose and chitin binding proteins E7and E8 the CBM33 proteins which improve cellulose hydrol-ysis mediated through exoglucanases [36 40 42] Cellulasesfrom T bifida have also been found showing synergism withendocellulases and Trichoderma reesei CBHI [6]

Cellulomonas fimi is a facultative anaerobe but it does notconsist of cellulosomes of cellulolytic anaerobes rather it pro-duces free cellulases [46] Similarly facultatively anaerobicCellulomonas flavigena also secrets free cellulases [46] Bothcarry out efficient hydrolysis of celluloses and hemicelluloses

The cellulase enzyme systems in Cellulomonas fimi also con-sist of six cellulases [39] that is three endocellulases (CenACenB and CenD) two exocellulases (CbhA and CbhB) anda processive endocellulase CenC [41 46] All these enzymeshave activities similar to that inT bifida with same families ofCBDs (2CBD) and catalytic domains but different sequences[41 47] These cellulases are primarily secreted by sec depen-dent pathway [46] and therefore do not require intracellularfolding or cofactors for their activity InC fimiATCC484 andC flavigena ATCC 482 another enzyme GH94 (cellobiosephosphorylase) has also been discovered [46] Microbisporabispora also shows synthesis of six different cellulases show-ing exo-exo and endo-exo synergism [6] Genomic studiesof Streptomyces sp SirexAA-E (ActE) isolated from pine-boring woodwasp Sirex noctilio have also shown genes forGH48 (CBH activity) GH74 (endocellulase) and CDB33[48] Streptomyces coelicolor consisted of 221 carbohydrateactive enzymes (CAZy) or 154 glycosyl hydrolases (GHs)encoded within 86 billion bp long genome [48]

The expression of cellulolytic genes in T bifida is inducedby cellobiose whereas easily utilizable sugar glucose showscatabolite repression as in most of the other cellulolyticmicrobes [49]The regulation of cellulolytic genes ismediatedby the CelR repressor which binds to a 9ndash14 bp palindrome

(51015840-TGGGAGCGCTCCCA-31015840) in region 51015840-upstream of thecellulase genes in the absence of cellobiose or cellulose [50]During induction cellulose is hydrolysed to cellobiose byconstitutive cellulases Cellobiose binds to CelR releasing itfrom the promoter allowing transcription of the downstreamgenes [47] In addition to the presence of glucose cellulasegenes expression is also regulated by cAMP levels

The extracellular cellulases are secreted by actinomycetesusing either one or both of the common bacterial systemsfor secretion of extracellular proteins that is sec generalsecretion system and sec independent twin-arginine translo-cation (TAT) systems The general Secretion route catalysestransmembrane translocation of proteins in their unfoldedconformation whereas Twin-arginine (TAT) system translo-cates secretory proteins in their native folded state InT bifidaboth of these systems were discovered whereas S coelicolormainly utilizes TAT systems for protein export [40]

32 Hemicellulases Hemicellulases are generally synthesisedalong with cellulases [36 39] Xylan and mannan are mostabundant components of hemicelluloses Complete hydroly-sis of xylan involves an enzyme system consisting of endo-14-120573-xylanases (EC 3218) 120573-D-xylosidases (EC 32137)120572-L-arabinofuranosidases (EC 32155) 120572-glucuronidases(EC 321139) acetyl xylan esterases (EC 31172) and fer-uliccoumaric acid esterases (EC 31173) Mannan is hydrol-ysed primarily by synergistic action of mannanases (EC32178) 120573-mannosidases (EC 32125) and 120572-galactosidases(EC 32122) [36 51] Mannanases hydrolyze 120573-14-glycosidicbonds internally 120573-mannosidase cleave 120573-14 linked man-nose from nonreducing ends and 120572-galactosidase removesterminal D-galactosyl residues linked by 120572-16 linkages [52]Degradation of mannan and xylan also enhances cellulosehydrolysis as they are known to inhibit cellulase activities[36]

Most of the hemicellulases belong to glycosyl hydrolasesfamilies however some enzymes involved in hemicellulosehydrolysis belong to glycosyltransferases (EC 241x) [39]Xylanases hydrolysing internal 120573-14-glycosidic bonds areclassified into GH families 5 7 8 10 11 and 43 120573-D-xylos-idases hydrolyse xylose monomers from nonreducing endsof xylan oligosaccharides and belong to GH families 3 3943 52 and 54 [53] Studies have indicated production ofseveral xylanases by T bifida and other actinomycetes Tbifida has been found to be producing 120573-14-endoxylan-ases (xyl10A xyl10B and xil11A) xylosidases 120572-L-arabino-furanosidases xyloglucanases 120573-13-glucanases (GH81) and120572-N-arabinofuranosidases (xil43) [36 40] Cellulomonas fimisynthesises extracellular endo- as well as exo-xylanases xylanbinding domain CBM4 120573-mannanase mannosidase andxel74 (xyloglucan specific 120573-14-glucanase) [36 46] Cellu-lomonas flavigena ATCC 482 are known to synthesize anunusual mixture of 19 endoxylanases along with GH10GH11 and GH30 xylanases GH43 (120573-xylosidase) GH51 120572-arabinofuranosidase and 120572-glucuronidase GH26 and GH13mannans and GH16 and GH81 120573-glucanase [46] Strepto-myces flavogriseus has shown production of 120573-14-glucan glu-canohydrolase [54] Xylanase genes GH5 (120573-mannosidase)

GH10 (beta xylanase) GH11 (beta xylanase) CE4 (acetylxy-lan esterase) and GH6 (CBH) and GH9 (CBH) have alsobeen found in Streptomyces sp SirexAA-E (ActE) [48]

33 Lignolytic Enzymes Lignin degradation is mediated bya complex of enzymes containing three principal enzymeslaccases (EC 11032) manganese peroxidases (MnP EC111113) and lignin peroxidases (LiP EC 111114) [55 56]Laccases are the oxidoreductases which degrade polyphenolthe principal recalcitrant component in the lignocellulose [1557] They are extracellular inducible enzymes which employsimple oxygen as an oxidizing agent as well as cofactorThey are multicopper oxidases having four copper atoms intheir active sites taking part in oxygen reduction [58] Lowsubstrate specificity of laccases enables them to degrade widevariety of compounds Manganese and lignin peroxidasesare together known as heme peroxidases containing proto-porphyrin IX as a prosthetic group Lignin peroxidases canspecifically degrade high redox potential compounds and areknown to oxidize phenolic as well as nonphenolic aromaticrings which make up around 90 of the lignin polymerThey require H

attractive substrate for LiP which oxidises other substratesby acting as the redox mediator for indirect oxidation Man-ganese peroxidases are low redox potential heme peroxidasesrequiring H

2O2for their activity They can be manganese

dependent or versatile peroxidases [56 58]Laccases or Laccase-likemulticopper oxidases containing

(LMCO) four copper atoms are classified in types 1 2 and3 [57 59] The four copper atoms are distributed in threedomains in most of the bacterial and fungal laccases [60]Structural studies in several actinomycetes however haverevealed presence of two Cu-binding domains rather thanthree [61 62] The two-domain structure has been named assmall laccase or small LMCO [59 61] LMCOs in Strepto-myces griseus Streptomyces cyaneus Streptomyces coelicolorStreptomyces ipomoea Streptomyces sviceus Streptomyces spand Thermobifida fusca are active as dimers or trimmers[61 63 64]

4 Genetic Engineering

The genes from several lignocellulolytic actinomycetes havebeen successfully cloned to show heterologous expression indifferent microbes GH1 and GH3 enzymes of C fimi ATCC484 expressed in E coli have shown efficient hydrolysis ofcelluloses and xylanases [65] CelStrep gene from cellulolyticStreptomyces sp G12 cloned and expressed in E coli wasfound to belong to GH12 family and catalysed hydrolysis ofcarboxymethylcellulose following aMichaelis-Menten kinet-ics with a 119870

119898of 913mgmL and a 119881max of 3469 120583Mminminus1

[66] Streptomyces reticuli consists of Cel1 gene encodingfor avicelase enzyme which alone can hydrolyse crystallinecellulose effectively [67] When this gene was cloned andexpressed in E coli Bacillus subtilis and Streptomyces sppenzyme was produced but in lower amounts probably dueto the absence of genes encoding for essential regulatoryfactors [68] From xylanolytic Actinomadura sp strain FC7two genes xylI and xylII have been cloned expressed and

well characterized in Streptomyces lividans [69] Xylanasegene xylBS27 belonging to GH11 from Streptomyces sp S27has been successfully cloned and expressed in Pichia pastorishydrolysing xylan to xylobiose [70] Similarly expression oflaccase gene from Streptomyces coelicolor (SLAC) in Strepto-myces lividans produced large amount of high purity laccase(350mg Lminus1) [71] The gene for a thermostable laccase fromStreptomyces lavendulae REN-7 was successfully cloned andexpressed in E coli [72] Cloning of a lignin peroxidase fromStreptomyces viridosporus T7A into Streptomyces lividansTK64 has resulted in better lignocellulose degradation bygenetically engineered S lividans compared to S lividansTK64 [73] Thus genetic engineering techniques can be andare being used for constructing industrially valuable strainswith potent applications based on actinomycetes lignocel-lulolytic enzymes

5 Diversity of Lignocellulolytic Actinomycetes

51 Cellulolytic Actinomycetes Cellulolytic potential of acti-nomycetes has been explored since inspection of othermicroorganisms for cellulase production Various researchstudies support high cellulose degradation potential ofmicrobes from actinomycetales Table 1 represents the diver-sity of actinomycetes producing cellulase enzymes

52 Hemicellulolytic Actinomycetes Diverse types of actino-mycetes belonging to wide range of habitats and active indifferent environmental conditions are known to producehemicellulolytic enzymes Streptomyces have been found tobe the most abundant hemicellulases producer among acti-nomycetes In a study by Boroujeni et al [74] all of theisolated hemicellulolytic actinomycetes were found to belongto Streptomyces genus Xylanase has been successfully puri-fied from Streptomyces sp E-86 and characterized for itsxylanolytic activity [75] Optimization studies were carriedout for endoxylanase production by Streptomyces sp F2621isolated from Turkey [76] 120573-xylosidase activity of Strepto-myces has been used in saccharification of ball milled wheatstraw [77] A thermostable xylanase was obtained from Strep-tomyces sp QG-11-3 which has shown biobleaching effects ineucalyptus kraft pulp [78] Xylanase has also been producedfrom other strains of Streptomyces sp such as Streptomycessp strain C1-3 [79] Streptomyces sp CD3 [80] Streptomycessp 7b [81] Streptomyces sp PC22 Streptomyces sp 234P-16ISWU-10 Streptomyces sp MDS [82] and Streptomyces sp[83] In Streptomyces rochei and Streptomyces chromofuscusxylanase production has been achieved using treated Papyrusand cotton stalk pulp The obtained xylanase when used forstudying bleaching effects has shown enhanced brightness inthe presence of EDTA [84] Xylanases have also been obtainedfrom Streptomyces albus and Streptomyces hygroscopicus andhave shown successful production of biogas using oil cakeand straw waste [85]

In a study by Ninawe et al [86] three Streptomyces iso-lates that is Streptomyces cyaneus S tendae and S caelestiswere found to be xylanolytic and the enzyme from Strep-tomyces cyaneus was successfully purified followed with its

characterization [87] Streptomyces thermoviolaceus OPC-520 exhibited production of acetyl xylan esterases and 120572-L-arabinofuranosidases enzymes [88] Extracellular xylanaseproduction has also been observed in Streptomyces aureofa-ciens [89] and in Streptomyces coelicolor grown on differentagricultural wastes such as sugarcane bagasse pineappleorange and pomegranate peels [90] Xylanases from Strep-tomyces albus and Streptomyces chromofuscus have indicatedpositive bleaching effects in rice straw pulp [91] Bhosale et al[92] have shown production of 326 IUmL of xylanases fromStreptomyces rameus using sugarcane bagasse along withpeptone and dextrose [92] Studies have indicated productionof cellulase free xylanases from Streptomyces roseiscleroticus[93 94] and Saccharomonospora viridis [95] Improvement inxylanase production has been documented in Streptomycespseudogriseolus subjected to UV mutagenesis [96] Xylanaseproduction has also been seen in Thermomonospora fusca[77 97]Thermomonospora curvataThermomonospora albaMicromonospora Microbispora bispora Nocardia Saccha-romonospora viridis and Thermoactinomyces have shownproduction of 120573-xylosidases acetylesterases and arabinofu-ranosidases [77] Extracellular xylanases have been partiallypurified and characterized in Microbispora siamensis in astudy by Boondaeng et al [98] Xylanase production has alsobeen observed inMicrotetraspora flexuosa [99] Streptomyceschattanoogensis UAH 23 [100] Streptomyces chattanoogensisCECT 3336 [101] Streptomyces violaceoruber [102] Ther-moactinomyces thalophilus [103]Thermomonospora sp [104]Streptomyces thermocyanaeviolaceus [105] and Streptomyceslividans [106] The enzyme from Streptomyces lividans waspurified and characterized by different researchers [107 108]Microbispora sp has been found to be producing hemicellu-lolytic mannanase enzyme [109] whereas other studies haveindicated production of 120573-xylosidases by Streptomyces albo-griseolus S nitrosporeus and Micromonospora melanosporea[110]

53 Lignolytic Actinomycetes Lignolytic activity is exhibitedby diverse range of actinomycetes which play importantrole in biodegradation processes in the environment Searchis in progress for more actinomycetes with high lignolyticpotential using advanced techniques combinedwith conven-tional methods A study by Fernandes et al [111] have usedspecifically designed primers for detection of laccase-likegeneswithin actinomycetes andhas identified gene fragmentsundetectable by known primers which corresponded tosuperfamilies I and K based on laccase and multicopperoxidase engineering database Arias et al [112] have shownproduction of laccase by Streptomyces cyaneus CECT 3335using soya flour Laccase was purified and characterizedand was found to show increase in brightness of eucalyptuskraft pulp in biobleaching studies The enzyme was able tooxidize veratryl alcohol suggesting potential of the strainin industrial applications Veratryl alcohol oxidation andother lignolytic activities have also been demonstrated inStreptomyces viridosporus [113 114]

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

(51015840-TGGGAGCGCTCCCA-31015840) in region 51015840-upstream of thecellulase genes in the absence of cellobiose or cellulose [50]During induction cellulose is hydrolysed to cellobiose byconstitutive cellulases Cellobiose binds to CelR releasing itfrom the promoter allowing transcription of the downstreamgenes [47] In addition to the presence of glucose cellulasegenes expression is also regulated by cAMP levels

The extracellular cellulases are secreted by actinomycetesusing either one or both of the common bacterial systemsfor secretion of extracellular proteins that is sec generalsecretion system and sec independent twin-arginine translo-cation (TAT) systems The general Secretion route catalysestransmembrane translocation of proteins in their unfoldedconformation whereas Twin-arginine (TAT) system translo-cates secretory proteins in their native folded state InT bifidaboth of these systems were discovered whereas S coelicolormainly utilizes TAT systems for protein export [40]

32 Hemicellulases Hemicellulases are generally synthesisedalong with cellulases [36 39] Xylan and mannan are mostabundant components of hemicelluloses Complete hydroly-sis of xylan involves an enzyme system consisting of endo-14-120573-xylanases (EC 3218) 120573-D-xylosidases (EC 32137)120572-L-arabinofuranosidases (EC 32155) 120572-glucuronidases(EC 321139) acetyl xylan esterases (EC 31172) and fer-uliccoumaric acid esterases (EC 31173) Mannan is hydrol-ysed primarily by synergistic action of mannanases (EC32178) 120573-mannosidases (EC 32125) and 120572-galactosidases(EC 32122) [36 51] Mannanases hydrolyze 120573-14-glycosidicbonds internally 120573-mannosidase cleave 120573-14 linked man-nose from nonreducing ends and 120572-galactosidase removesterminal D-galactosyl residues linked by 120572-16 linkages [52]Degradation of mannan and xylan also enhances cellulosehydrolysis as they are known to inhibit cellulase activities[36]

Most of the hemicellulases belong to glycosyl hydrolasesfamilies however some enzymes involved in hemicellulosehydrolysis belong to glycosyltransferases (EC 241x) [39]Xylanases hydrolysing internal 120573-14-glycosidic bonds areclassified into GH families 5 7 8 10 11 and 43 120573-D-xylos-idases hydrolyse xylose monomers from nonreducing endsof xylan oligosaccharides and belong to GH families 3 3943 52 and 54 [53] Studies have indicated production ofseveral xylanases by T bifida and other actinomycetes Tbifida has been found to be producing 120573-14-endoxylan-ases (xyl10A xyl10B and xil11A) xylosidases 120572-L-arabino-furanosidases xyloglucanases 120573-13-glucanases (GH81) and120572-N-arabinofuranosidases (xil43) [36 40] Cellulomonas fimisynthesises extracellular endo- as well as exo-xylanases xylanbinding domain CBM4 120573-mannanase mannosidase andxel74 (xyloglucan specific 120573-14-glucanase) [36 46] Cellu-lomonas flavigena ATCC 482 are known to synthesize anunusual mixture of 19 endoxylanases along with GH10GH11 and GH30 xylanases GH43 (120573-xylosidase) GH51 120572-arabinofuranosidase and 120572-glucuronidase GH26 and GH13mannans and GH16 and GH81 120573-glucanase [46] Strepto-myces flavogriseus has shown production of 120573-14-glucan glu-canohydrolase [54] Xylanase genes GH5 (120573-mannosidase)

GH10 (beta xylanase) GH11 (beta xylanase) CE4 (acetylxy-lan esterase) and GH6 (CBH) and GH9 (CBH) have alsobeen found in Streptomyces sp SirexAA-E (ActE) [48]

33 Lignolytic Enzymes Lignin degradation is mediated bya complex of enzymes containing three principal enzymeslaccases (EC 11032) manganese peroxidases (MnP EC111113) and lignin peroxidases (LiP EC 111114) [55 56]Laccases are the oxidoreductases which degrade polyphenolthe principal recalcitrant component in the lignocellulose [1557] They are extracellular inducible enzymes which employsimple oxygen as an oxidizing agent as well as cofactorThey are multicopper oxidases having four copper atoms intheir active sites taking part in oxygen reduction [58] Lowsubstrate specificity of laccases enables them to degrade widevariety of compounds Manganese and lignin peroxidasesare together known as heme peroxidases containing proto-porphyrin IX as a prosthetic group Lignin peroxidases canspecifically degrade high redox potential compounds and areknown to oxidize phenolic as well as nonphenolic aromaticrings which make up around 90 of the lignin polymerThey require H

2O2for their activity Veratryl alcohol is an

attractive substrate for LiP which oxidises other substratesby acting as the redox mediator for indirect oxidation Man-ganese peroxidases are low redox potential heme peroxidasesrequiring H

2O2for their activity They can be manganese

dependent or versatile peroxidases [56 58]Laccases or Laccase-likemulticopper oxidases containing

(LMCO) four copper atoms are classified in types 1 2 and3 [57 59] The four copper atoms are distributed in threedomains in most of the bacterial and fungal laccases [60]Structural studies in several actinomycetes however haverevealed presence of two Cu-binding domains rather thanthree [61 62] The two-domain structure has been named assmall laccase or small LMCO [59 61] LMCOs in Strepto-myces griseus Streptomyces cyaneus Streptomyces coelicolorStreptomyces ipomoea Streptomyces sviceus Streptomyces spand Thermobifida fusca are active as dimers or trimmers[61 63 64]

4 Genetic Engineering

The genes from several lignocellulolytic actinomycetes havebeen successfully cloned to show heterologous expression indifferent microbes GH1 and GH3 enzymes of C fimi ATCC484 expressed in E coli have shown efficient hydrolysis ofcelluloses and xylanases [65] CelStrep gene from cellulolyticStreptomyces sp G12 cloned and expressed in E coli wasfound to belong to GH12 family and catalysed hydrolysis ofcarboxymethylcellulose following aMichaelis-Menten kinet-ics with a 119870

119898of 913mgmL and a 119881max of 3469 120583Mminminus1

[66] Streptomyces reticuli consists of Cel1 gene encodingfor avicelase enzyme which alone can hydrolyse crystallinecellulose effectively [67] When this gene was cloned andexpressed in E coli Bacillus subtilis and Streptomyces sppenzyme was produced but in lower amounts probably dueto the absence of genes encoding for essential regulatoryfactors [68] From xylanolytic Actinomadura sp strain FC7two genes xylI and xylII have been cloned expressed and

well characterized in Streptomyces lividans [69] Xylanasegene xylBS27 belonging to GH11 from Streptomyces sp S27has been successfully cloned and expressed in Pichia pastorishydrolysing xylan to xylobiose [70] Similarly expression oflaccase gene from Streptomyces coelicolor (SLAC) in Strepto-myces lividans produced large amount of high purity laccase(350mg Lminus1) [71] The gene for a thermostable laccase fromStreptomyces lavendulae REN-7 was successfully cloned andexpressed in E coli [72] Cloning of a lignin peroxidase fromStreptomyces viridosporus T7A into Streptomyces lividansTK64 has resulted in better lignocellulose degradation bygenetically engineered S lividans compared to S lividansTK64 [73] Thus genetic engineering techniques can be andare being used for constructing industrially valuable strainswith potent applications based on actinomycetes lignocel-lulolytic enzymes

5 Diversity of Lignocellulolytic Actinomycetes

51 Cellulolytic Actinomycetes Cellulolytic potential of acti-nomycetes has been explored since inspection of othermicroorganisms for cellulase production Various researchstudies support high cellulose degradation potential ofmicrobes from actinomycetales Table 1 represents the diver-sity of actinomycetes producing cellulase enzymes

52 Hemicellulolytic Actinomycetes Diverse types of actino-mycetes belonging to wide range of habitats and active indifferent environmental conditions are known to producehemicellulolytic enzymes Streptomyces have been found tobe the most abundant hemicellulases producer among acti-nomycetes In a study by Boroujeni et al [74] all of theisolated hemicellulolytic actinomycetes were found to belongto Streptomyces genus Xylanase has been successfully puri-fied from Streptomyces sp E-86 and characterized for itsxylanolytic activity [75] Optimization studies were carriedout for endoxylanase production by Streptomyces sp F2621isolated from Turkey [76] 120573-xylosidase activity of Strepto-myces has been used in saccharification of ball milled wheatstraw [77] A thermostable xylanase was obtained from Strep-tomyces sp QG-11-3 which has shown biobleaching effects ineucalyptus kraft pulp [78] Xylanase has also been producedfrom other strains of Streptomyces sp such as Streptomycessp strain C1-3 [79] Streptomyces sp CD3 [80] Streptomycessp 7b [81] Streptomyces sp PC22 Streptomyces sp 234P-16ISWU-10 Streptomyces sp MDS [82] and Streptomyces sp[83] In Streptomyces rochei and Streptomyces chromofuscusxylanase production has been achieved using treated Papyrusand cotton stalk pulp The obtained xylanase when used forstudying bleaching effects has shown enhanced brightness inthe presence of EDTA [84] Xylanases have also been obtainedfrom Streptomyces albus and Streptomyces hygroscopicus andhave shown successful production of biogas using oil cakeand straw waste [85]

In a study by Ninawe et al [86] three Streptomyces iso-lates that is Streptomyces cyaneus S tendae and S caelestiswere found to be xylanolytic and the enzyme from Strep-tomyces cyaneus was successfully purified followed with its

characterization [87] Streptomyces thermoviolaceus OPC-520 exhibited production of acetyl xylan esterases and 120572-L-arabinofuranosidases enzymes [88] Extracellular xylanaseproduction has also been observed in Streptomyces aureofa-ciens [89] and in Streptomyces coelicolor grown on differentagricultural wastes such as sugarcane bagasse pineappleorange and pomegranate peels [90] Xylanases from Strep-tomyces albus and Streptomyces chromofuscus have indicatedpositive bleaching effects in rice straw pulp [91] Bhosale et al[92] have shown production of 326 IUmL of xylanases fromStreptomyces rameus using sugarcane bagasse along withpeptone and dextrose [92] Studies have indicated productionof cellulase free xylanases from Streptomyces roseiscleroticus[93 94] and Saccharomonospora viridis [95] Improvement inxylanase production has been documented in Streptomycespseudogriseolus subjected to UV mutagenesis [96] Xylanaseproduction has also been seen in Thermomonospora fusca[77 97]Thermomonospora curvataThermomonospora albaMicromonospora Microbispora bispora Nocardia Saccha-romonospora viridis and Thermoactinomyces have shownproduction of 120573-xylosidases acetylesterases and arabinofu-ranosidases [77] Extracellular xylanases have been partiallypurified and characterized in Microbispora siamensis in astudy by Boondaeng et al [98] Xylanase production has alsobeen observed inMicrotetraspora flexuosa [99] Streptomyceschattanoogensis UAH 23 [100] Streptomyces chattanoogensisCECT 3336 [101] Streptomyces violaceoruber [102] Ther-moactinomyces thalophilus [103]Thermomonospora sp [104]Streptomyces thermocyanaeviolaceus [105] and Streptomyceslividans [106] The enzyme from Streptomyces lividans waspurified and characterized by different researchers [107 108]Microbispora sp has been found to be producing hemicellu-lolytic mannanase enzyme [109] whereas other studies haveindicated production of 120573-xylosidases by Streptomyces albo-griseolus S nitrosporeus and Micromonospora melanosporea[110]

53 Lignolytic Actinomycetes Lignolytic activity is exhibitedby diverse range of actinomycetes which play importantrole in biodegradation processes in the environment Searchis in progress for more actinomycetes with high lignolyticpotential using advanced techniques combinedwith conven-tional methods A study by Fernandes et al [111] have usedspecifically designed primers for detection of laccase-likegeneswithin actinomycetes andhas identified gene fragmentsundetectable by known primers which corresponded tosuperfamilies I and K based on laccase and multicopperoxidase engineering database Arias et al [112] have shownproduction of laccase by Streptomyces cyaneus CECT 3335using soya flour Laccase was purified and characterizedand was found to show increase in brightness of eucalyptuskraft pulp in biobleaching studies The enzyme was able tooxidize veratryl alcohol suggesting potential of the strainin industrial applications Veratryl alcohol oxidation andother lignolytic activities have also been demonstrated inStreptomyces viridosporus [113 114]

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

well characterized in Streptomyces lividans [69] Xylanasegene xylBS27 belonging to GH11 from Streptomyces sp S27has been successfully cloned and expressed in Pichia pastorishydrolysing xylan to xylobiose [70] Similarly expression oflaccase gene from Streptomyces coelicolor (SLAC) in Strepto-myces lividans produced large amount of high purity laccase(350mg Lminus1) [71] The gene for a thermostable laccase fromStreptomyces lavendulae REN-7 was successfully cloned andexpressed in E coli [72] Cloning of a lignin peroxidase fromStreptomyces viridosporus T7A into Streptomyces lividansTK64 has resulted in better lignocellulose degradation bygenetically engineered S lividans compared to S lividansTK64 [73] Thus genetic engineering techniques can be andare being used for constructing industrially valuable strainswith potent applications based on actinomycetes lignocel-lulolytic enzymes

5 Diversity of Lignocellulolytic Actinomycetes

51 Cellulolytic Actinomycetes Cellulolytic potential of acti-nomycetes has been explored since inspection of othermicroorganisms for cellulase production Various researchstudies support high cellulose degradation potential ofmicrobes from actinomycetales Table 1 represents the diver-sity of actinomycetes producing cellulase enzymes

52 Hemicellulolytic Actinomycetes Diverse types of actino-mycetes belonging to wide range of habitats and active indifferent environmental conditions are known to producehemicellulolytic enzymes Streptomyces have been found tobe the most abundant hemicellulases producer among acti-nomycetes In a study by Boroujeni et al [74] all of theisolated hemicellulolytic actinomycetes were found to belongto Streptomyces genus Xylanase has been successfully puri-fied from Streptomyces sp E-86 and characterized for itsxylanolytic activity [75] Optimization studies were carriedout for endoxylanase production by Streptomyces sp F2621isolated from Turkey [76] 120573-xylosidase activity of Strepto-myces has been used in saccharification of ball milled wheatstraw [77] A thermostable xylanase was obtained from Strep-tomyces sp QG-11-3 which has shown biobleaching effects ineucalyptus kraft pulp [78] Xylanase has also been producedfrom other strains of Streptomyces sp such as Streptomycessp strain C1-3 [79] Streptomyces sp CD3 [80] Streptomycessp 7b [81] Streptomyces sp PC22 Streptomyces sp 234P-16ISWU-10 Streptomyces sp MDS [82] and Streptomyces sp[83] In Streptomyces rochei and Streptomyces chromofuscusxylanase production has been achieved using treated Papyrusand cotton stalk pulp The obtained xylanase when used forstudying bleaching effects has shown enhanced brightness inthe presence of EDTA [84] Xylanases have also been obtainedfrom Streptomyces albus and Streptomyces hygroscopicus andhave shown successful production of biogas using oil cakeand straw waste [85]

In a study by Ninawe et al [86] three Streptomyces iso-lates that is Streptomyces cyaneus S tendae and S caelestiswere found to be xylanolytic and the enzyme from Strep-tomyces cyaneus was successfully purified followed with its

characterization [87] Streptomyces thermoviolaceus OPC-520 exhibited production of acetyl xylan esterases and 120572-L-arabinofuranosidases enzymes [88] Extracellular xylanaseproduction has also been observed in Streptomyces aureofa-ciens [89] and in Streptomyces coelicolor grown on differentagricultural wastes such as sugarcane bagasse pineappleorange and pomegranate peels [90] Xylanases from Strep-tomyces albus and Streptomyces chromofuscus have indicatedpositive bleaching effects in rice straw pulp [91] Bhosale et al[92] have shown production of 326 IUmL of xylanases fromStreptomyces rameus using sugarcane bagasse along withpeptone and dextrose [92] Studies have indicated productionof cellulase free xylanases from Streptomyces roseiscleroticus[93 94] and Saccharomonospora viridis [95] Improvement inxylanase production has been documented in Streptomycespseudogriseolus subjected to UV mutagenesis [96] Xylanaseproduction has also been seen in Thermomonospora fusca[77 97]Thermomonospora curvataThermomonospora albaMicromonospora Microbispora bispora Nocardia Saccha-romonospora viridis and Thermoactinomyces have shownproduction of 120573-xylosidases acetylesterases and arabinofu-ranosidases [77] Extracellular xylanases have been partiallypurified and characterized in Microbispora siamensis in astudy by Boondaeng et al [98] Xylanase production has alsobeen observed inMicrotetraspora flexuosa [99] Streptomyceschattanoogensis UAH 23 [100] Streptomyces chattanoogensisCECT 3336 [101] Streptomyces violaceoruber [102] Ther-moactinomyces thalophilus [103]Thermomonospora sp [104]Streptomyces thermocyanaeviolaceus [105] and Streptomyceslividans [106] The enzyme from Streptomyces lividans waspurified and characterized by different researchers [107 108]Microbispora sp has been found to be producing hemicellu-lolytic mannanase enzyme [109] whereas other studies haveindicated production of 120573-xylosidases by Streptomyces albo-griseolus S nitrosporeus and Micromonospora melanosporea[110]

53 Lignolytic Actinomycetes Lignolytic activity is exhibitedby diverse range of actinomycetes which play importantrole in biodegradation processes in the environment Searchis in progress for more actinomycetes with high lignolyticpotential using advanced techniques combinedwith conven-tional methods A study by Fernandes et al [111] have usedspecifically designed primers for detection of laccase-likegeneswithin actinomycetes andhas identified gene fragmentsundetectable by known primers which corresponded tosuperfamilies I and K based on laccase and multicopperoxidase engineering database Arias et al [112] have shownproduction of laccase by Streptomyces cyaneus CECT 3335using soya flour Laccase was purified and characterizedand was found to show increase in brightness of eucalyptuskraft pulp in biobleaching studies The enzyme was able tooxidize veratryl alcohol suggesting potential of the strainin industrial applications Veratryl alcohol oxidation andother lignolytic activities have also been demonstrated inStreptomyces viridosporus [113 114]

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors

6 Future Prospects

Owing to the abundance and renewability of lignocellulosicbiomass it is considered as most appropriate and econom-ical feedstock for production of various industrially usefulproducts Lignocellulases enzymes are therefore critical inprocesses associated with bioconversion of lignocellulosesPresently most of the commercially exploited lignocellulasesrely on fungal or bacterial microorganisms Actinomycetesare relatively less explored for their biomass hydrolysispotential The studies can be elaborated in search of newactinomycetes producing lignocellulose degrading enzymesystemsDifferent feedstock shows variation in their chemical

composition The production of enzymes needs to be opti-mized for different biomass The production of lignocellu-lases from all microbial sources is still quite expensiveEfforts can be made for reducing the cost of productionof these enzymes using high potency actinomycete enzymesystems with broader range of tolerance and active at diverseenvironmental conditions Genetic engineering techniquescan be used to construct enzyme systems with desirablecharacteristics Also the studies can be expanded gradually toscale up to the industrial levels for their subsequent adoptionin commercial processes

7 Conclusion

Actinomycetes are an important source of lignocellulosehydrolysing enzymes They constitute considerable propor-tion of the soil or aquatic microflora responsible for biomassdegradation in nature The research studies on search oflignocellulose hydrolysing actinomycetes revealed the abun-dance and diversity of these microbes in different ecologicalniches The genetic and protein studies on their hydrolyticenzymes lead to the elucidation of structural and mecha-nism details of enzymes and their relatedness with otherknown lignocellulose producers and their enzyme systemsRelatively scanty information is available on lignocellulolyticactinomycetes The research studies therefore need to beelaborated in view of utilization of lignocellulolytic potentialof actinomycetes applicable in different industrial sectors
