Lignocellulosic Biopolymers: from Cell Wall Assemblies to Synthons for Green Chemistry

I am leader of the IJPB research team Apsynth where I investigate lignin structural variability and functionalities for a better use of biorefinery recalcitrant waste. I coordinated the Zelcor project (H2020 BBI-JU) and I am responsible for the Master degree Bioceb.

Scientific objectives
Through my research and teaching activities, I develop an integrated approach of lignin valorisation. This approach aims at reducing the environmental impact and improving competitivity of lignocellulose biorefineries, following a « zero-waste » objective. Together with the organic chemists and biochemists of the Apsynth team, I exploit the structural diversity and multifunctionality of these phenolic compounds to design new routes for the production of functional moleucles (antioxidants), polymers for plastics, or chemical intermediates. These works imply collaborations with industrial partners producing lignins (paper industry and biorefinery) and with endusers (building sector, plasturgy, cosmetics). They benefit from a network of academic experts of chemical, physico-chemical and biological biomass-conversion. I wish to reinforce in the years to come the interactions with teams involved in the plant selection and engineering, in order to demonstrate the possibility to take into account lignin quality criteria as soon as plant production, and identify in planta some structures of gognitive or applied interest.

Major results
  • Reinforcement of the water resistance of thermoplastic starch films by electron-beam irradiation in the presence of lignins
  • Influence of oxidative systems and their implementation conditions on the polymerisation of lignin precursors in vitro
  • Interest of combining lignin fractionation and lignin depolymerisation by ionic liquids to produce antioxidant oligomers
  • Lignin modification induced by fungal and bacterial oxido-reductases

Projects and networks : European projects H2020 Zelcor (BBI-JU 2016-2020) and MILIMO (ERA CoBioTech 2020-2023); ANR project Funclipro (2020-2023); Institut Carnot 3BCar GDR Symbiose Competitiveness cluster « Industries and Agro-Resources » (IAR)



Teaching
I coordinate trainings in the field of Bioeconomy at AgroParisTech. I supervise the engineer track « Biorefiney – Green chemistry » (2nd et 3rd year AgroParisTech), and the Erasmus + Master Bioceb (M1-M2) attached to the Mention « Biologie Intégrative et Physiologie » of the Université Paris-Saclay (School BASE). Co-leader of the Domain Committee « Ingénierie des aliments, biomolécules et énergie » of AgroParisTech, I favour pluridisciplinary courses, related to industry and including practical activities (visit of industrial sites, projects, international mobility …).
