The Max Planck Institute for Marine Microbiology

During two thirds of our earth’s history, microorganisms ruled the planet. They developed an impressive diversity of species and metabolic pathways. Also today, microorganisms are playing a key role in shaping our earth and climate.

At the Max Planck Institute for Marine Microbiology (MPIMM), we study microorganisms in the sea and other waters. Which role do they play, what are their characteristics, how diverse are they? How do they contribute to the global elemental cycles of carbon, nitrogen, sulfur and iron? What does that mean for our environment and climate? Researchers from all over the world, engineers, technicians and many more at the MPIMM work hard to answer these and many other questions. Their expertise spans from microbiology to microsensors, geochemistry to genome analysis and molecular ecology to modelling.

Founded in 1992, the MPIMM is part of the Biology & Medicine section of the Max Planck Society (MPG). Since 2002, we also run the International Max Planck Research School of Marine Microbiology (MarMic), a M.Sc. / Ph.D. graduate program for highly qualified and motivated national and international students. MarMic is a joint program of the MPIMM, the University of Bremen, the Alfred Wegener Institute for Polar and Marine Research and the Jacobs University Bremen.
