Topic "Adaptation mechanisms and bacterial diversity"

The research in the theme "Adaptation mechanisms and bacterial diversity" aims at extending the knowledge on adaptation mechanisms through integrated analyses of their genetic and phenotypic diversities. The team evaluates the mechanisms involved in the health properties of bacteria (GABA metabolism, ability to ferment plant sugars in L. lactis, resistance to nanoparticles in commensal strains of E. coli, etc.) and their technological potential (aroma production, acidification capacity of L. lactis, etc.) These studies are conducted in the framework of pure strains but also in consortia to increase functional diversity. In particular, the team explores the interactions between 1) L. lactis strains, 2) lactic acid bacteria species, 3) heterogeneous subpopulations of E. coli coexisting during nutritional transitions.
