Marine Molecular Microbiology

The research interests of the group concern marine microbial ecology. We apply molecular and microbiological tools to identify factors that regulate bacterioplankton community composition in the ocean. Recent and ongoing projects are especially related to the ecology of heterotrophic N2-fixing bacterioplankton and bacterial diversity and population dynamics.

In parallel with the microbiology projects, we apply molecular tools in projects adressing aspects of plankton ecology. Current projects concern molecular identification of fish larvae and their prey.

Standard microbiology techniques and bacterial cultivation are combined with state-of-the-art molecular methodology such as: PCR, Real-Time PCR, metagenomics, transcriptomics and amplicon sequencing. Approaches include field work as well as experimental work.
