Quorum sensing in Roseobacter : Interactions between fish probiotic Roseobacter and fish pathogenic bacteria: Mode of action and application in aquaculture

The purpose of the project is to determine the role of QS molecules in community structure and life style of roseobacters. Specifically, we will study if their antagonistic activity and interactions with fish pathogenic bacteria can be manipulated via the QS system. We will determine if QS molecules regulate biofilm formation and production of antagonistic compounds in model systems using laboratory substrates but also in algal and rotifer cultures mimicking both the natural environment and the aquaculture scenario.
