SUMMARY:Soutenance HDR de Julien PERARD (Irig/LCBM)
DESCRIPTION:From iron to biohydrogen: how bacteria are inspiring the biotechnologies of tomorrow\nRésumé : \nMicroorganisms play a crucial role in biotechnologies\, enabling the transformation of matter into high-value gases and biomass. At a time when the climate emergency demands a rethinking of our energy models\, my work is part of a responsible research approach\, aiming to reconcile scientific excellence\, environmental sustainability\, and economic viability.​\nOver the past twelve years\, I have dedicated my career to understanding the molecular mechanisms of the Fur and SUF systems (Fe-S cluster biogenesis\, bacterial virulence) and to studying nickel insertion into CO dehydrogenase\, using integrated structural approaches (SAXS\, MALLS\, crystallography). Since 2021\, I have refocused my research on energy biotechnologies. After a brief overview of my scientific journey\, I will detail my projects on developing solutions for BioH₂ production and CO₂ valorization\, particularly through the « Bioraffinery » project (combining photofermentation and methanogenesis)\, inspired by my participation in the 2022 EIC Horizon Prize. I have optimized photobioreactors (PBRs)\, improving their light efficiency and achieving up to 5 mol H₂/mol of substrate from PLA waste.​\nToday\, I am working on optimizing microbial strains and culture conditions\, as well as integrating circular processes for the joint production of BioH₂/BioCH₄. In collaboration with Génoscope\, CEA Tech\, and industrial partners\, I have developed advanced biorafineries to convert by-products into biofuels.​\nMy work\, at the interface of biophysics\, enzymology\, and engineering\, is part of a decarbonized bioeconomy approach.​ \n_ \nContact : alain.farchi@cea.fr
