Significance of particle-associated marine bacteria producing secondary metabolites (Volkswagen Foundation, Lower Saxony).

The aim of this project is to isolate hitherto unknown particle-associated marine bacteria in the Wadden Sea which produce secondary metabolites which may be of interest to medical or biotechnological applications. We are particularly interested in the ecological significance of these metabolites. It is embedded into a state-wide research priority program of Lower Saxonia and a joint project with the Institute of Organic Chemistry at the University of Göttingen (Prof. Axel Zeeck).
