Research

Functional stability of syntrophic consortia involved in anaerobic contaminant degradation.

Contamination of large areas with organic pollutants on former or still in use sites used by chemical industry and via accidents (e.g. Deep Water Horizon) is a widely distributed circumstance. The aerobic degradation processes of these pollutants are well investigated and described and can be used for bioremediation purposes. In contrast, knowledge about degradation processes under anaerobic conditions exhibit several gaps.

Therefore, my research is focussed on the investigation of a syntrophic consortia present in the [aquifer] of the industrial site Zeitz. One target aims on key players and participants of the benzene degradation pathway and elucidating their role in the appropriate processes using a combination of genomic and proteomic techniques (e.g. stable [isotope] methods based on feeding with 13C-labelled substrate). Further investigations examine the influence of abiotic factors (e.g. terminal [electron acceptor], surface material) on the consortia structure and degradation performance.


I am supervised by Dr. Carsten Vogt (Department of Isotope Biogeochemistry) and Dr. Sabine Kleinsteuber (Department of Environmental Microbiology). The project is embedded in POF III T4.
