DFG-Heisenberg-Group "Archaeal Life in the Ocean"

In the Marine Archaea Group we are interested in the physiology, ecology, biochemistry and biogeochemistry of a widely distributed and highly abundant phylogenetic group of microorganisms, the Archaea. Members of the phylogenetic domain Archaea occur in various marine habitats and catalyze essential reactions in the marine nutrient cycles. With our research group with strong expertise in Marine Microbiology and Biogeochemistry we apply comprehensive approaches combining the cultivation of marine archaea with state-of-the-art geochemical and molecular biological methods in order to understand the role of archaea in the marine environment. We are associated with the Organic Geochemistry Group of Prof. Kai-Uwe Hinrichs at the MARUM and collabarate closely with well-established local (Univeristy of Bremen and the MPI for Marine Microbiology) and international (e.g. University of Vienna, University of Washington, Harvard University) research groups.
The independent group was established in 2016 and is financially supported by the Deutsche Forschungsgemeinschaft via a DFG-Heisenberg Fellowship awarded to Martin Könneke.
