Chemical ecology and microbial communication

Environmental microbiology, Cell to cell communication in the environment, Chemical Ecology, Quorum-sensing, Biotechnological applications.


With over one million of cells per milliliter of seawater, bacteria are key players in the functioning of marine ecosystems. Many studies have focused on abiotic factors regulating these communities, but biotic factors , such as cell to cell communication (quorum-sensing), remain poorly understood. Although a large number of studies have been conducted on interesting strains for medical applications, the signaling molecules diversity in the environment, their expression patterns and their effects on natural communities remain poorly explored. This research has a particular importance in many ecological contexts: the importance of this microbial communication is strongly suspected in causing severe shellfish mortalities, termination of toxic phytoplankton blooms, the development of emerging diseases of protected species in several reserves and marine parks. These issues are addressed at the lab combining the tools of traditional microbiology (culture-based approaches), environmental genomics and chemistry of natural substances.
