Team presentation

The FARE research unit is working on the mechanisms of deconstruction of lignocellulosic plant resources in natural ecosystems for agriculture and the environment and in (bio) technological processes for green and sustainable chemistry. In the value chain of agricultural and forestry resources, FARE's application and innovation objectives relate to i / upstream, the maintenance of soil fertility, carbon storage and the control of greenhouse gas emissions. and ii / downstream, the production of molecules, fibers and agro-sourced materials. All of FARE's actions are part of the national and European development of sustainable and circular economies.

FARE is working on two themes related to agroecology and bioeconomy :

The first theme concerns mainly the study of biological processes of lignocellulosic biomass deconstruction or biodegradation (in field or reactor) using phenomenological and mechanistic approaches (e.g., interaction and cooperation between macro- and microbiomes; between microbial and enzymatic consortia) and modelling approaches of the systems studied (e.g., dynamic structural modelling of the biological deconstruction of plant cell walls, modelling of decomposition and enzyme efficiency in soils, modelling of microbial growth on lignocellulose).

The second theme focuses on the use of fractionation products obtained from lignocellulose for chemistry and materials using different approaches. A central point is the search for functionalities that are intrinsic to these fractions (e.g., anti-oxidant, film forming and optical properties) or designed by rationale transformations/modifications (surfactants, compatibilisation of composites, etc.). The processes can be biological (enzymes, microorganisms), physicochemical (polymer self-assemblies, extrusion), or a combination of elementary operations (chemo-enzymatic reactions, reactive extrusion, etc.). The targeted applications are molecules, polymers and materials with high added value or new properties, mainly on the basis of FARE’s research and patents (nanomaterials, molecules and biobased surfactants, fibrous materials, etc.).

To complete the two abovementioned themes, two cross-cutting activities are implemented: (i) to integrate knowledge, to orientate the experimental strategy and support-the decisions through modelling approaches; (ii) to manage simultaneously environmental and technological quality of biomass at the level of the transformation of lignocellulose and their further uses (trade offs between ecosystem services and ecoconception of products)
