Head of the group of Molecular Enzyme Technology and Biochemistry (Faculty of Chemistry) at the University of Duisburg-Essen. My research interest is the central carbohydrate metabolism of (hyper)thermophilic Archaea and its regulation, with a special focuss on stress response. The aim is to gain a systems level understanding by the combination of modern highthrouput analyses with classical biochemistry and molecular biology.
My research is intended to contribute to the elucidation of the physiological and molecular processes involved in the biofilm formation of acidophilic leaching bacteria with emphasis in their cell-cell communication mechanisms.
In SysMetEx, our role is to understand biofilm formation at a microscopical and OMICS levels, in order to optimize it.
Background- Thermophilic organisms are composed of both bacterial and archaeal species. The enzymes isolated from these species and from other extreme habitats are more robust to temperature, organic solvents and proteolysis. They often have unique substrate specificities and originate from novel metabolic pathways. Thermophiles as well as their stable enzymes (‘thermozymes’) are receiving increased attention for biotechnological applications.
The proposed project will establish thermophilic in
Biomining is a biotechnological process carried out in many parts of the world that exploits acid loving microorganisms to extract metals from sulphide minerals. One industrial biomining method is called ‘heap bioleaching’ where typically copper containing minerals are piled into very large heaps, acid and microorganisms are added to the top and the soluble metal is collected at the heap base.
The role of the different types of microbes in the process is to speed up metal solubilisation by oxidising
