SCIENTIFIC THEMATICS and ORGANIZATION OF THE TEAM

The human intestinal microbiota, as we know it today, appears to be very complex. In order to move towards a holistic understanding of the gut microbiota, including its non-cultivable component, which is still in the majority to date, we have contributed to the development of a new and powerful approach, metagenomics, which has enabled rapid progress in the characterisation of the genomic and genetic diversity of the gut microbiota. For example, the microbial genome (microbiome) of each individual contains ~28 times more genes than the human genome. The microbiota is, moreover, considered to be a host organ in its own right.
The FInE team aims to deepen the current understanding of the fundamental role played by the microbiota in human health. Our objective is to better understand the mechanisms of the human-microbe symbiosis and the influence of our diet, in particular the importance of fibre, polyphenols and probiotics, in order to define strategies for its modulation.
FInE is a joint team linked to the MICA and AlimH departments of INRAE. It is closely linked to MetaGenoPolis since it contributed to the emergence of two of its platforms (SAMBO and MétaFun).
Our theme is based on several themes carried out by the team's researchers and supported by 4 technical workshops and a fermenter platform in collaboration with MGP
