The research conducted by MCAM scientists is situated at the interface between chemistry, biology, and ecology. Our studies focus on the characterization of biomolecules, from metabolites to proteins, and the mechanisms regulating interactions between various microorganisms and their surrounding environment or host. The MCAM unit utilizes a wide diversity of model microorganisms (bacteria, archaea, cyanobacteria, fungi, protists, and nematodes). Our multidisciplinarity allows for an integrated approach linking molecules produced by microorganisms to their subsequent impacts on the surrounding ecosystems.
