Research

Aim of my PhD thesis is the development of a high-pressure incubation system for microorganisms. This work is part of the Projekt GeoEn (GeoEnergy) funded by the Federal Ministry of Education and Research, which is a collaboration of the German Research Center for Geosciences (GFZ Potsdam), the University of Potsdam and the Brandenburg University of Technology in Cottbus (BTU). Within the framework of this projekt the possibilities of geological energy production and the avoidance of climate changing by energy production (CO2 capture and storage) shall be investigated.

The high-pressure system will be used for the cultivation of microorganisms living under (biological) high pressures. This is necessary be cause certain metabolic processes are running with different velocities and to different products under modfied pressures. Also many reaction compounds that are participated (gases, chem. compounds) are present in different concentrations. Furthermore metabolic rates can be investigated under these in-situ conditions. The achieved pressure of 500 bar are equivalent to 5000 m depth of the ocean.

Furthermore I am working on the sulfate reduction in mud volcanoes. In these geological structures microorganisms are transported with the stream of mud from depth with higher pressure to the surface.
