Presentation

This theme focuses on the production, extraction, purification and characterization of biomolecules such as proteins and polysaccharides from plant and microbial biomasses.

Their implementation as biological, techno-functional agents and materials is handled to better comprehend structures/functions relations.

In a multi-scale approach, the work undertaken:

• involves the development of process diagrams for the selective and fractional extraction of the different classes of biomolecules,
• requires the implementation of complex analytical tools for the structural characterization of biomolecules,
• is based on engineering sciences (chemical engineering, rheology, industrial microbiology ...) and life sciences (structural biochemistry, enzyme engineering, microbiology).

There are multiple applications of this work and they cover various domains:

• plant or microbial biomass fractionation processes according to a biorefinery strategy
• processes for the fine purification of biomolecules by filtration and chromatography techniques
• the use of biomolecules in several fields of application (biological assets, hydrocolloids, biosourced materials).
