Cyanobacteria are photosynthetic bacteria that populate extremely diverse environments like soil crusts, open oceans, deserts, hot springs, permafrost and glacial regions, or have adopted a symbiotic lifestyle. They have produced the oxygenic atmosphere on Earth and are the ancestors of chloroplasts. We are investigating regulatory systems and adaptation strategies of cyanobacteria on a molecular level. We intend to focus our work on a model cyanobacterium with a well-annotated genome and simple genetic manipulation systems in order to characterize specific cyanobacterial functions that also might be relevant for future biotechnological applications. Main current projects include investigations on phototaxis using different photoreceptors, circadian clock and the role of regulatory RNA in cyanobacteria. In addition, we are working on several applied projects elucidating the potential of cyanobacteria as producers of amino acids, proteins as well as biofuels.
