Internship subjects

TA Unit

Internship subject 1:

“Influence of yeast fermentation on bread nutritional, technologic and

organoleptic qualities”

Baked goods being an essential constituent in the diet of most populations, their improvement and

fortification could be considered as an effective approach for developing high quality and healthy

products.

The intensity of food transformation could result in different properties of the food itself, its molecular

composition and also different « health » properties for the consumer. As an example, in traditional

French baguette, we have already shown the impact of baking time on the production of Maillard

reaction products (MRP) (Jouquand et al. 2018), revealing different organoleptic properties and

modulating sub-species of the intestinal microbiota leading to potential health impact.

Thus, the objective of this project is to investigate, through modulation of some parameters in the

bread-making process (e.g. choice of starting material such as microbial populations, microbial

enzymatic activity, flour source), the technological, organoleptic, nutritional properties of the bread as

well as the impact on bread digestibility by intestinal microbiota and the modulation of this microbiota

and metabolic luminal environment as early markers of health outcomes.

Mission

During the internship, the main objective will be to create different bread models by using different

yeast strains and different fermentation conditions. Textural (dought elacticity), nutritional

(melanoidins) and organoleptic (aroma compounds) properties as well as protein digestibility will be

evaluated for these bread models.

“Dairy cows databases exploitation to improve farm performances” Livestock production systems are changing towards precision livestock management allowing a better

respect of the environment and animal welfare, as a growing demand by consumers. In particular,

dairy cows systems have seen an increase in robotization in the past 20 years mainly concerning

milking, feeding, reproduction or even animal’s behaviour. Robotization makes possible a constant

monitoring (24/7) as well as a more optimal performance per cow. This high technology led to a

reduction in the number of animals housed on farm allowed by an increase in their production.

In our centre, concentrate consumption and milk yield for each producing animal have been recorded

and stored by DeLaval robot every day from 2006. Similarly, health status, reproduction data and other

welfare indicators have been manually registered every month and compiled in a different database.

The analysis of these data may provide more indicators of performance in dairy systems, such as the

optimal number of lactations (and/or its duration) per cow according to its physiological state or even

to reproduction or welfare indicators. However, this information is very difficult to obtain due to the

existence of several databases, the nature of information (qualitative or quantitative), or differences

in time measurements, for example.

The main objective of this master project is therefore to obtain simple and practical precision

equations based on the information collected on our farm in order to help breeders in key decisions

about the future of their animals.

Mission

To achieve this goal, the specific missions are the following:

1) Literature review on the subject and the statistical models to be used; 2) Harmonizing all the information presented in our databases; 3) Statistical analysis of the results; 4) Choice of prediction equations and verification with some animals of our farm; 5) Publication results in a relevant journal (depending on time)

Academic level: Last year of undergraduate degree or Master degree in Agronomy, with a

background or an experience in animal production.

“Influence of the transformation process parameters undergone by plant

material for non food-use applications”

The agro-resources are convertible in to materials for various non-food domains (plastics, composite,

building materials …). Agro-resources are composed of various biochemical macromolecules (pectins,

cellulose, hemicelluloses, lignines, wax, starch, proteins …) and their proportions vary with the

botanical species and the localization in the plant. Thus, agro-ressources can be considered as complex

composites. During transformation of raw materials, these biochemical compositions are modified

under influence of the physical and chemical parameters. Some processes use this reactive specificity.

In this intership, we suggest studying the influence of parameters of processes, well known by our

research team, on chemical and physico-chemical modifications of the agro-resources. One of the first

transformations which undergo fiber plants is the retting. This process takes place in the field when

the plants stalks were lifted from the soil and deposited in swaths. Then the stalks undergo the

combined action of heat, humidity and microorganisms. The research work realized by the VAM²IN

team shows that the variability of the plant material coming from different maturity and retting

degrees and transformation process influence the functionnalies of agro-materials. Functionalities can

have a positive impact (like thermal isolation, cohesion between particles, reduction of materials

weight, ignifugation, acoustic) or a negative impact (inhibition of mineral binder setting).

By determining the biochemical composition of the agro-resource (hemp) before and after process,

we identify the natural molecules which are responsible and/or involved in the transformations. Then,






with commercial molecules, we can imitate the effect of the transformations parameters (ozone, pH,

temperature) on the chemical modifications (oxidation, degradation, molecular breakdown) and

consequences on the physico-chemical behavior (cristallinity, viscosity, hydrophily) of

macromolecules.

Mission

Fractioning of the hemp and identification of its composition and its leachates

Impact of the temperature, the pH and the ozone on the modification of identified molecules

thanks to models based on isolated commercial molecules

Impact of chemical modifications on physico-chemical behavior of molecules

Study around the hypothesis explaining adhesion/inhibition mechanisms between

components of agro-materials

This project is part of the research axes of the "Transformation & AgroRessources" team:

• Construction and functionalization of new biobased materials

• Deconstruction of agro-resources for the production of bio-sources

“Study of the oxidation of monosaccharides and derivatives by Ozone

technology”

In a context of sustainable development, chemists are increasingly concerned by regulations banning

the use of certain chemicals (REACH regulation). Moreover, the petroleum material is a non-renewable

resource, the industrialists seek to substitute their petrochemical ingredients with biomolecules

derived from the agricultural raw material. Oxidized sugars (gluconic acid, glucuronic acid and oxidized

polysaccharides) are molecules that can meet these regulatory and raw material constraints. At

present, the processes used to oxidize carbohydrates use reagents such as nitric acid, potassium

permanganate, hydrogen peroxide and they are concerned by REACH.

These reagents are all more or less effective depending on the nature of the substrates studied and

the conditions used (temperature, pH of the medium, solvent) and give relatively satisfactory reaction

yields. However, at a time when consumer demands are becoming more and more environmentally

friendly, research laboratories and chemical manufacturers feel obliged to find methods of oxidation

that are less polluting and more respectful of the environment while respecting the economic aspect.

Today, two clean and non-polluting technologies can answer to these constraints: ozone and

electrochemistry. Electrochemistry is an oxidation reduction reaction. The disadvantage of this

method is the frequent fouling of the electrode which prevents oxidation from taking place and leads

to poor performance.

This problem becomes a limiting factor in industry because it is necessary to regularly clean the

electrode, or even change it, which makes this oxidation technique very expensive. Ozone is an

oxidation method that is already used in industry: bleaching of pulp, water treatment. This process

also makes it possible to oxidize the carbohydrate units, whether it be monosaccharides or

polysaccharides. Apply to monosaccharides, ozone allows the synthesis of biomolecules that can be

used as surfactants in the field of cosmetics.

Mission

• Study of the oxidation of monosaccharides and derivatives (monosaccharides grafted by

unsaturated fatty acids). The oxidation conditions will be investigated:

o Molecular ozone action (under acidic or neutral conditions)





o Radical ozone action (in basic conditions)

o Synthesis of new surfactants

Identification of the products formed

o By chromatographic methods coupled to mass: GC / MS; LC / MS

o By "infrared" methods: FT / IR.

o RVA and Brookfield for viscosity analysis.

This project is part of the research axes of the "Transformation & AgroRessources" team:

• Construction and functionalization of new biobased materials

• Deconstruction of agro-resources for the production of bio-sources

“Evolution of the microbial populations constituting the activated sludge,

after introduction of micro-pollutants in the communal or industrial

wastewater ”

In the Wastewater Treatment Plants, activated sludge (AS), a consortium of organisms, degrades organic matter and treats nitrogen and phosphorus. For urban sewage treatment efficiencies are well controlled. However, the bio-recalcitrant organic matter, generally composed of organic micro-pollutants, is eliminated only partially or not at all by conventional biological treatment. The origin of this pollution results from human activity for urban wastewater. Indeed, we find in the urine and faeces medicinal residues such as anti-biotics, anti-inflammatories, anti-epileptics ... These small molecules in urban wastewater could disrupt activated sludge activity and alter mapping microbial community. Following a physicochemical modification of the culture medium by the introduction of micro-pollutants, the species involved in the purification of waste water, both bacteria and more complex organisms (protozoa, metazoans) constituting activated sludge try to adapt in the new environment. Some species may disappear in favor of the expansion of other species. Thus, after several days of modification of the environment, the population finally observed may be different from that at the start, both in terms of the species present and in the number of individuals. Techniques exist to evaluate this population evolution, but they are expensive and not widely available. It would be interesting to have a simple technique, fast, and easy to apply during work on the biodegradation of recalcitrant molecules by activated sludge. A project started in September 2016 with the ECAM (Dr Jean-Marc Laferté) as part of the work of students of the EME and the ECAM. The EME brings its expertise and work on water treatment and more particularly micro-pollutants of pharmaceutical origin and the ECAM its skills and work on Deep Learning. This project has developed knowledge about the organisms involved in the treatment of wastewater (activated sludge) for EME and Deep Learning for ECAM.

Mission

The objective of this study is to follow over time the evolution of the microbial population constituting the activated sludge, after introduction of micro-pollutants (alone or in mixture) in the communal or industrial wastewater. in parallel with the microbiological study (microscope observation and use of computer software developed by ECAM), physico-chemical measurements (pH, conductivity, turbidity, dry matter, suspended solids, COD, BOD5, respirometry test, settling test …) will be carried out in order to correlate them with the evolution of the activated sludge population. The ultimate goal is to provide




wastewater treatment companies with a methodology to quickly assess in situ the malfunctions of their wastewater treatment plant and allow them to react quickly.

“Process intensification in the removal of bacterial pathogens and organic constituents from synthetic slaughterhouse wastewater using innovative

photocatalysis” Context In many developing countries, slaughterhouse effluents can be discharged directly into watercourses and lakes without any prior treatment, which creates a favorable environment for microorganisms’ proliferation that diffuse into the water (microbiological contamination). However, some microorganisms are the cause of disease and death. In a similar way, it is well known that slaughterhouse facilities use vast volumes of water daily for cleaning procedures, including carcass blood washing, equipment sterilization. Therefore, this specific




pollution (chemical contamination) can be found in the environment and have negative effects on health and environment. Facing this problem, we will study the photocatalytic treatment of bacterial pathogens and organic constituents of a synthetic slaughterhouse wastewater. The general idea is, on the one hand to activate persulfate by metal cations such as Fe2+ (already present in blood hemoglobin of slaughtered animals) and Co2+. On the other hand, UV radiation will be used to optimize the generation of sulfate radicals SO4°, an oxidant known for its ability to eliminate both microorganisms and chemical pollution. The most targeted microorganisms in this project are enterobacteria. Regarding chemical pollution, we will seek to reduce Total Organic Carbon (TOC) in these effluents. Mission As the successful candidate for this internship, your main missions and activities will be as follows: 1. Literature review of the state of the art of using integrated processes activate persulfate/ photocatalysis for emerging pollutants (chemical and microbiological contaminations) elimination in water. 2. Photocatalytic degradation/mineralization of a model molecule will be performed in batch reactors. Experiments will be investigated to activate persulfate and by using UV radiation to optimize sulfate radicals for the reduction of TOC and bacterial counts. 3. A perspective of this study will be to identify new catalysts and carry out the treatment feasibility in continuous mode. 4. Identification of the intermediate products formed in the photocatalytic degradation and reaction pathways

“Characterize the growth in several conditions (medium, pH) of the previously

isolated BCAs which had shown an ability to suppress or strongly inhibit A.

euteiches development”

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, is a large, economically and medicinally important family of flowering plants. This family has the ability to biologically fix atmospheric nitrogen via rhizobial symbionts. Under optimal environmental conditions, most of their nitrogen demand can be supplied by nitrogen fixation, and nitrogen resources in the soil may even be increased (Unkovich and Pate, 2000).

Aphanomyces euteiches is the causal agent for root rot of a wide range of leguminous crops (pea, alfalfa, beans, and clovers). Symptoms caused by A. euteiches are very similar in all hosts but vary in timing or intensity (Hughes and Grau, 2007). This oomycete is world widespread and is considered one of the main soilborne agents impairing yields, especially for pea culture for which losses can reach up to 100% (Gaulin et al., 2007). Unfortunately, there is no specific fungicide available to control it. Without a chemical solution, biological control of root rot caused by A. euteiches has provided a vast field of investigation since the 1990s. Several microorganisms (King and Parke, 1993; Wakelin et al., 2012) showed encouraging effects in vitro but application to field conditions showed only slight or no effect on root rot emergence and intensity.

In a previous work in the laboratory, biological control agents (BCA) against Aphanomyces euteiches naturally present in Normandy soils, has been assessed under different crop covers (pea, fababean, rapeseed). Culturable bacteria have been extracted and isolated. A first screening has allowed to discriminate 17 isolates which strongly reduced or totally inhibited in vitro development of A. euteiches mycelium.

Mission



The aim of this Master proposal is first to characterize the growth in several condition (medium, pH) of the previously isolated BCAs which had shown an ability to suppress or strongly inhibit A. euteiches development. These isolates will be then tested for their compatibility and effect on the growth of some varieties of spring and winter peas (without pathogen) in an inert culture matrix, at several inoculum densities. Finally the efficiency of the compatible BCA to protect the studied varieties of pea against rot root will be determined in microcosm experiment with artificial pathogen inoculation (symptoms notation, growth follow-up, evaluation of root architecture, etc.). A focus will be particularly done on the optimal inoculum density of BCAs to maximize plant protection according to pathogen pressure.

“Assessing the susceptibility of pea varieties to Phytopathogen Aphanomyces

euteiches”

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, is a large, economically and medicinally important family of flowering plants. This family has the ability to biologically fix atmospheric nitrogen via rhizobial symbionts. Under optimal environmental conditions, most of their nitrogen demand can be supplied by nitrogen fixation, and nitrogen resources in the soil may even be increased (Unkovich and Pate, 2000). Aphanomyces euteiches is the causal agent for root rot of a wide range of leguminous crops (pea, alfalfa, beans, and clovers). Symptoms caused by A. euteiches are very similar in all hosts but vary in timing or intensity (Hughes and Grau, 2007). This oomycete is world widespread and is considered one of the main soilborne agents impairing yields, especially for pea culture for which losses can reach up to 100% (Gaulin et al., 2007). Unfortunately, there is no specific fungicide available to control it. Without a chemical solution, biological control of root rot caused by A. euteiches has provided a vast field of investigation since the 1990s. Among the different investigations to counteract the telluric pathogen, the varietal selection seems to be one of the most potential alternative. Field observations seem to show that winter peas are more resistant to Aphanomyces euteiches than spring varieties. In order to understand this observation, preliminary results obtained in our laboratory seem to show that it’s much more complex than that.

Mission

The aim of this Master proposal is: - 1) to assess the susceptibility of 3 winter and 3 spring pea varieties to Aphanomyces euteiches in controlled conditions and characterize the plant phenotypes (leaf and root systems) - 2) to assess protein root profiles which can explain the susceptibility or tolerance to Aphanomyces euteiches development. Differential protein profiles will be then analyzed by MS-MS.

“Unravelling the role of phosphorus (P) forms on the efficacy of renewable P

sources to improve P availability”

Although phosphorus (P) is essential for all living organisms, it acts as a limiting nutrient for the

productivity of many agrosystems due to its low availability in soil which results from its low solubility

(precipitation) and its strong affinity for mineral surfaces. P fertilization is therefore needed to meet

the crop demand and achieve high yields. Most of the P currently used in chemical fertilizers is derived

from phosphate rocks that are finite and located in only a few places on Earth. Moving towards more

sustainable sources for managing P in cropping systems, renewable nutrient-rich (derived-)organic

amendments (manure, sludge, compost, biochar, ashes, struvite …) are increasingly considered to

replace P fertilizers produced from phosphate rocks, not only by scientists but also by politics and

stakeholders (see the launch of the revision of the Fertilizer Regulation in EU,

http://europa.eu/rapid/press-release_IP-16-827_en.htm). However, compared to conventional P

fertilizers such as triple superphosphate, P is present in these amendments in various inorganic and

organic forms which differ in their plant availability. Most of the research investigating the fate of P

applied to the soil has focused on inorganic phosphate, showing that most of it was sorbed onto clays

and Fe- and Al-oxides or precipitate with Ca, which, in turn, mediate its availability for plants. By

contrast, the fate of other P forms has been disregarded so far. Moreover, since plant species differ in

their ability to mobilize P from soil P pools, it is highly likely that the potential of recycled P fertilizers

to increase plant uptake will be dependent not only on the forms of P but also on the P

mobilization/acquisition strategies (e.g. soil acidification, carboxylate secretion, phosphatase release

…) used by the plants. Thus, in order to optimize the use of recycled P fertilizer and to be able to predict

P availability in cropping systems, there is a great challenge to elucidate the relationships between the

forms of P applied to the soil, the soil properties and the plant traits involved in the P

mobilization/acquisition and their consequences on P mobility and uptake by plants.

Mission

The main objective of this PhD project is to optimize the use of renewable P fertilizers through a better

understanding of the impact of P forms on P availability in contrasted soil-plant systems (Figure 1). The

first step of this PhD project will be to identify the soil constituents and properties which are involved

in the sorption/desorption of P applied under different forms. The knowledge of these parameters will

be of help to predict the availability of P as a function of the form which is applied and to better model

the behavior of P according to the soil properties. The second step will be to validate the results of the

sorption/desorption experiments by analyzing the P uptake by plants in response to the application of

various P forms. Since most of the renewable P fertilizers differ also in terms of nitrogen (N)

concentration and organic carbon (C) composition (e.g. cellulose, hemicellulose, lignin) which can in

turn impact physico-chemical and biological soil properties, the third step will be to evaluate the effect

of these compounds on the P uptake. The first three steps will be carried out using single inorganic and

organic P compounds, applied alone or in mixture, and ryegrass will be used as the test plant. The final

step will consist to evaluate the genericity of our data by testing the effect of “real” amendments

(struvite, sludge, biochar …) with contrasted P forms on P mobility and uptake by plants. In this step,

plants with different P mobilization/acquisition traits will be tested alone (single-species treatment) or

in combination (multi-species treatment). We hypothesize that the overall uptake of P will be higher

in multi-species than in single-species treatments and, more importantly, the addition of a mixture of

inorganic and organic P forms will result in higher P use efficiency by multi-species treatment than the

addition of only one P form.

« Family Agriculture and agrifood business: Issues, challenges and future

directions”

To what extend family business is worsed to be studied? First because in Europe more than 60% of

farming and companies are family owned ones and 83% in France (European Commission, 2017).

Besided their contribution to the economy, family firms bring stability due to their long term strategy

towards stakeholders’ interests, social responsibility due to the importance of family value transfer to

future generations. Second, because family firms are different from other firms because of the

relationships and the dynamics between the family and the business systems (Carrigan and Buckley,

2008). This provides to these firms specific advantages in building relationships especially with

customers and stakeholder groups (Biberman, 2001). But what about the agriculture and the agrifood

sector?

Because a big number of them are family owned, this project master will be focused on the case of

family firms in the agriculture and the agrifood sector. More particularly, the objective is to understand

issues, challenges and future directions of these family firms. The environmental and food issues that

challenge agriculture and the agrifood sectors are the key topics for this project master. Particular

attention will be devoted to the topic of innovation: what kind of sustainable innovation are conducted

by family firms? How do family owned firms manage innovation?

Methodology:



Literature review, semi-structured interviews with farmers and managers of family owned firms in

France.

Framing:

The Master Thesis will be supervised by Maryem Cherni, PhD, Associate professor of Strategy and

Innovation Management at Institut Polytechnique Unilasalle, Transversal Sciences of Engineering and

Management Department, Member of INTERACT Research Unit, 19 Rue Pierre Waguet, 60000

“Identifying which are the bacteria more effective to make a symbiotic

relationship with each of the legume crop presented in a panel of worldwide

pulses”

There is an increasing debate about the importance of plant-based proteins and the diversification of protein sources for food or feed destination (De Boer & Aiking, 2011). Plant-based proteins originate in several botanical families but are mainly concentrated in legumes. Several scholars have been interested in grain legumes because of their role as a source of food, feed and bioenergy/biomaterials but also because of the agro-ecosystem services they provide (Nemececk et al., 2008; Gan et al., 2015). On the one hand, despite their importance, grain legume consumption and production are declining worldwide (Ranalli 1995; Voisin et al., 2014) whereas only soybean area is continuously increasing, linked to the intensification of livestock production (Voisin et al., 2014). On the other hand, grain legume diversity from a worldwide perspective is very high, however, these species have local patterns of production and consumption in several developing countries (Ayerdi Gotor and Marraccini, 2015). At the same time, farmers of Western Europe arable crops are searching for diversification to shift into more sustainable and resilient cropping systems. One of the major crops targeted for diversification are grain legumes (Bowen and Hollinger, 2004; Wezel et al., 2014). However, there is a general lack of knowledge and references regarding these grain legumes in terms of production potential in Northern countries but also the potential use of these proteins for food, feed or no food purposes.

Objectives of the Master Thesis 1. The aim of this Master Thesis proposal is to identify which are the bacteria more effective to make a symbiotic relationship with each of the legume crop presented in a panel of worldwide pulses. As those crops are not grown in France it is necessary to test which bacteria should be inoculated before sowing to guarantee the farmers’yields. 2. Determination of the main physiological stage of growth of 5 main chosen species (i.e.: Sum of temperatures required to start flowering, start grain filling and harvest maturity…) 3. In parallel first experimentations on cold resistance of those species will be tested, in order to identify the earliest sowing date that farmers can expect.

Experiments will be conducted in climatic chamber and greenhouse.
