Bioremediation using microorganisms
Streptomycetes from a heavy metal containing site of the former uranium mining site Wismut in Eastern Thuringia are used to determine the mechanisms of heavy metal resistance in this group of important soil microbes and questions of bio-geo-interactions. Investigation of superoxide dismutase and other factors of heavy metal binding capacity are investigated by biochemical and molecular techniques. In addition, different plants, with bacteria and/or AM fungi are used for pot and field experiments to develop bioremediation approaches. The monitoring of microbial biodiversity in disturbed ecosystems is included in these investigations which are part of a Geo-Bio-Interaction group in collaboration with other researchers of the university and Wismut GmbH/WISUTEC.
Another focus is the investigation of bacterial diversity of different habitats, also with regard on ist geological background, like humic-acid coated sands, salt springs of the Thuringian bassin or radionuklide-containing water from different mines.
Further the degradation of polycyclic aromatic hydrocarbons using autochthonous microorganisms in contaminated gas plant areas is analysed, also focusing on the development of probable bioremediation approaches.
