Massive algae blooms appear in spring in certain bodies of water only to vanish within a number of weeks. In this video, BERNHARD M. FUCHS analyzes the degradation of such algae, exploring which organisms are involved and what they actually do. Employing methodologies involving ribosomal RNA, in situ hybridization and metagenome sequencing, Fuchs finds that a strikingly limited range of organisms (Flavobacteria) are active in this process and that their activities become increasingly complex over the duration of the algae bloom. Showing how genetic information can be used to predict ecological activity, the work makes a significant contribution to our understanding of the vital role played by microorganisms.

Researcher

Bernhard M. Fuchs is head of the research group Flow Cytometry in the Department of Molecular Ecology at the Max Planck Institute for Marine Microbiology. His research interests include the autecology of marine picoplankton populations as well as methodological innovation in the fields of flow cytometry and fluorescence in situ hybridization. Fuchs has completed contract work for AstraZeneca, BASF and Vermicon GmbH and he acts as a reviewer for the UK’s National Environmental Research Council (NERC), the French National Research Agency (ANR) and the German Science Foundation (DFG).

Institution

Max Planck Institute for Marine Microbiology

At the Max Planck Institute for Marine Microbiology (MPIMM), we are investigating microorganisms in the sea and other waters. What role do they play, what are their characteristics and how great is their biodiversity? What is the contribution of microorganisms to the global cycles of carbon, nitrogen, sulfur and iron? What does this mean for our environment and our climate? These and many other questions will be answered by researchers from around the world, engineers, technicians and numerous others at the MPIMM. Their fields of expertise range from microbiology to microsensors, geochemistry to genome analysis and molecular ecology to modelling. The MPIMM was founded in 1992 and is part of the Max Planck Society (MPG). Since 2002, the MPIMM has been running the International Max Planck Research School of Marine Microbiology ( MarMic ), a program for highly qualified master students and graduates of our institute and the Bremen Research Alliance partner Bremen University, Alfred Wegener Institute Helmholtz Center for Polar and Marine Research ( AWI ) and Jacobs University.
