Center for Microbial Communities

About CMC

The overall research mission of the Center for Microbial Communities (CMC) is to provide new fundamental understanding of structure and function of microbial communities in engineered and natural habitats. This provides insight into improved management of various microbial processes and advises how microbial communities can solve, in a sustainable way, some of the grand challenges the society faces.

CMC has currently approx. 35 researchers, primarily from Department of Chemistry and Bioscience, AAU. We have a close collaboration with researchers from Department of Microbiology and Ecosystem Science, University of Vienna, Austria, and Singapore Centre on Environmental Life Sciences Engineering (SCELSE), Nanyang Technological University, Singapore, besides many other national and international key institutions in the field. 

The Center for Microbial Communities (CMC) was founded in 2013 as an interdisciplinary research center funded by Aalborg University, Danish and German Research councils, the EU and additional support from industry and foundations
