Biochemical engineeringThe BioEnergy Home Pagehttp://calvin.biotech.wisc.edu/jeffries/This web resource for bioenergy, bioconversion, and bioprocess technology is maintained by Tom Jeffries at theUniversity of Wisconsin Biotechnology Center. Educationalsections include bioprocessing for liquid fuels from biomassfeedstocks, enzymatic methods for de-inking, bleaching, andrecycling paper, and an archive of related papers, graphics andfiles of frequently asked questions.

Recombinant Protein Expression Laboratoryhttp://www.cbs.umn.edu/bpti/RPEL.htmlThe Biological Process Technology Institute (BPTI) has establishedthe Recombinant Protein Expression Laboratory (RPEL) as a large-scale protein production and purification facility for researchers ofthe University of Minnesota. In addition to bacterial and yeastexpression, the RPEL essentially focuses on the baculovirus expres-sion vector system. This web page summarises the advantages ofthe baculovirus expression vector system and lists available vectors.

Frances Arnold’s WWW homepagehttp://www.che.caltech.edu/groups/fha/This site presents the research conducted by Frances Arnold atthe Division of Chemistry, Chemical Engineering andBioengineering of the California Institute of Technology. Herproject focuses on directed evolution and optimization ofenzymes for applications in biological systems, such as metabolic pathways and genetic circuits.

The Gene Delivery Group Websitehttp://web.bham.ac.uk/can4psd4/Designed and maintained by Phil Dash, the website of theGene Delivery Group at the University of Birmingham gives anintroduction to gene therapy and describes viral vectors as wellas non-viral vectors, including liposomes, cationic lipids, peptide-mediated gene delivery and naked DNA.

Chromatography Databasehttp://www.chromatography-db.com/This open database of high-pressure liquid chromatography(HPLC) chromatograms for liquid chromatography users, has beenjointly developed at the Institut Universitari de Ciència i Tecnoligia(IUCT) and Quimifarma Network – Cat World Network (CISP) inBarcelona. Chromatographic information can be retrieved either

using the chemical name of the compound or through a combinedsearch for the compound using the chemical name, type and value.

Plant biotechnologyPlant Pathology Internet Guide Bookhttp://www.bspp.org.uk/ppigb/bacterio.htmThe Plant Pathology Internet Guide Book is a very usefulresource guide for internet sites on plant pathology and all relatedfields. The extensive number of selected entries are classified bytopic and are briefly commented upon. One section is dedicated to virology. This resource is maintained by Thorsten Kraskaand is hosted by the British Society for Plant Pathology (BSPP).

Plant Viruses Online – Quick Introductionhttp://image.fs.uidaho.edu/vide/The Virus Identification Data Exchange (VIDE) project is supported by the Rural Credit Development Fund of theReserve Bank of Australia and by the Australian Centre forInternational Agricultural Research (ACIAR). The web server,accessible through the mirror site at the University of Idaho,provides an introduction to VIDE and alphabetical indexes ofviral species and genera, host plant species, virus nomenclatureand etymology. Access is available to relevant sites.

Transgenic Plantshttp://www.ultranet.com/~jkimball/BiologyPages/T/TransgenicPlants.htmlThe Kimball’s biology page on transgenic plants. This page summarises some of the new traits introduced into plants, such as improved nutritional quality, insect, disease and herbicide resis-tance, salt tolerance, and the ability to produce biopharmaceuticals.

Plantibodieshttp://www.sciam.com/1197issue/1197techbus1.htmlThis page from the Scientific American is written by Wayt Gibbson the use of field crops to produce human antibodies. This briefoverview covers safety, volumes and cost of production of anti-bodies used for the treatment of non-Hodgkin’s lymphoma andagainst herpes simplex virus 2. These plantibodies are producedin genetically engineered corn, soybean or tobacco.
