Cell-cell communication of bacteria of the Roseobacter clade with other bacteria and algae (B04)

• Subject Area: Microbial Ecology and Applied Microbiology ; Metabolism, Biochemistry and Genetics of Microorganisms
• Term: from 2010 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 34509606

This project will focus on the interaction of the dinoflagellate Prorocentrum minimum and the diatom Thalassiosira rotula with their phyco-microbiome. Axenic algal cultures will be inoculated with the model bacteria of the Roseobacter group D. shibae and P. inhibens to identify their influence on growth, metabolite production, and death of the algae in comparison to bacteria-free cultures and to those harbouring the natural algal phyco-microbiome. Further, outer membrane vesicles produced by D. shibae and their significance as a transmitter for DNA will be studied.
