Bioreactor Systems for (Co-)Cultivation of Phototrophic and Heterotrophic Microorganisms

Cyanobacteria are a class of bacteria known as the ancestors of today's chloroplasts and thus of plants. They also belong to the group of bacteria that perform oxygen photosynthesis and thus positively influence a large part of the world's climate. With the growth of the world population, the demand for renewable energy sources as well as chemicals and therapeutics is increasing, while a sustainable production of these compounds seems desirable. Cyanobacteria represent an alternative to the heterotrophic organisms traditionally used. They perform oxygen photosynthesis, using the energy of the sun, carbon dioxide (CO2) and water (H2O) to build up carbohydrates. This process also releases elemental oxygen (O2), which can be used by other organisms. In addition, cyanobacteria require only a minimal supply of nutrients and can be cultivated at many sites, which provides a large variable biotechnological applicability. The production of high-value terpene products as well as establishing co-cultivations is our current focus.
