Although many clinically and ecologically relevant processes are known to be performed by biofilm communities composed of strict or facultative anaerobic bacteria, biofilms were often studied in aerobic conditions. We use in vitro anaerobic culture systems combined with genetic and genomic approaches to study the molecular basis of biofilm formation by anaerobic commensal and pathogenic bacteria.
