Overview

We stud­y mi­cro­bial eco­logy in a wide range of en­vir­on­ments: seep sys­tems in the deep-sea, coastal sed­i­ments, coral reefs, an­oxic lakes, mi­cro­bial mats,  an­imal as­so­ci­ated mi­crobes and more. The re­search is highly di­verse, in­clud­ing pho­to­syn­thesis, ni­tro­gen and sul­fur cyc­ling, cal­ci­fic­a­tion, hab­itat map­ping, ecosystem productivity and cell physiology. Most themes in­volve the study of the func­tion­ing of in­tact mi­cro­bial com­munit­ies with non-in­vas­ive meth­ods that al­low as dir­ect an ob­ser­va­tion as pos­sible. To­gether with the MPI work­shops, we con­tinu­ously strive to de­velop novel meth­ods, and ap­ply them in our re­search. We col­lab­or­ate widely with other in­sti­tutes and with groups within the in­sti­tute to share know­ledge and ideas.

 
Study objects are:
· Microbial mats
· Deep-sea sediments
· Porous sandy intertidal plates
· Corals and foraminifera
· Fresh- and seawater biofilms
The processes investigated are:
· Photosynthesis
· Calcification
· Sulfate reduction
· Sulfide oxidation
· Nitrification
· Denitrification
 
 
 
Mass transfer phenomena are considered as regulating factor for process rates, e.g. advection by bioventilation, currents and tides.

The research is partially technology driven, and new sensors and sensing techniques are actively developed.
