Research overview
The mission of the MPI is to understand how microorganisms function at the molecular, cellular, and community levels. In particular, we aim to elucidate the mechanisms underlying the metabolic diversity of microorganisms, their ability to adapt and differentiate in response to changes in the environment, the mechanisms involved in cell cycle regulation and cell polarity as well as the biogeochemical processes involved in the exchange of climatically relevant trace gases. These analyses include all levels of microbial functions from the atomic/structural level, the molecular and cellular levels, and biochemistry/physiology to the microbial community level and plant–microbe interactions.

Research at the institute is carried out in three departments. In addition the institute hosts three Max Planck Research Groups, one Emeritus Group and two Max Planck Fellows.
