Microbial Ecophysiology

The Microbial Ecophysiology group at the University of Bremen is part of the Bremen Marine Ecology Centre for Research & Education (BreMarE) and associated with MARUM, Center for Marine Environmental Sciences. Our main research interests are anaerobic microbial processes in sediments and soils, and the functional biodiversity of microorganisms involved.
