Although competitive interactions between bacteria (bacterial interference), are likely to represent a key aspect of many infectious processes, the nature of these interactions within mixed biofilm communities is poorly understood. We use in vitro biofilm models […]

  Specific metabolic changes occurring during biofilm formation were hypothesized to lead to the production of biofilm-associated molecules and biofilm-specific functions. The  identification of biofilm-specific metabolites could reveal new aspects of biofilm biology, and lead to novel strategies […]

 One of the  of the hallmarks of biofilm physiology is its tolerance to a high level of antimicrobials. We are currently investigating the molecular mechanisms that lead to this transient ability to withstand antimicrobial treatments. […]

   Bacteria produce and release into their headspace a wide variety of volatile secondary metabolites. However, While detection and quantification of these volatiles as attractive or repellent odors and aromas are of great interest in food and cosmetic […]
