Topic 1 - Microbial Biodiversity and Chemodiversity

In this topic, our activities focus on the study of the diversity of microorganisms, the processes leading to the structuring of microbial diversity, and in turn, the role of microbial communities in the functioning of more complex systems (from holobionts to ecosystems).  We are particularly interested in understanding chemically mediated mechanisms involved in these processes, especially in symbiotic relationships. Therefore, the study of chemodiversity associated with microorganisms, in particular the discovery of new molecular structures, represents an important and significant part of research in this theme. While many of our studies focus on the microbiota associated with marine organisms (e.g., lichens, sponges and macrophytes), we are also studying interspecific interactions in other ecosystems. Cell-to-cell interaction processes, "quorum sensing", the chemical diversity of communication molecules and their functional role, in the regulation of biofilm formation for example, are also part of this theme. Finally, the activities related to the valorisation of molecules and extracts resulting from this research are part of this research theme

This is a large theme, in which is organized in several subthemes and activities.
