Project description
The project should demonstrate the potential of the purple bacterium Rhodospirillum rubrum for large-scale hydrogen production using fruit- and milk-wastes as substrates. This novel process ("dark photosynthesis") does not require light, is cheap to run, and readily up-scalable. Parallel to hydrogen production, the "dark photosynthetic" metabolic regime can be utilized for the simultaneous production of high-value industrial products, e.g. terpenoids. The "dark photosynthesis" process still allows the possible use of a low energy illumination for further enhancement of hydrogen production efficiency. It is intended that the project should be an important contributor to a future hydrogen economy and also circular bioeconomy in Germany. The future market potential of the "dark photosynthetic" process will be analyzed by a systematic study of the integration of the process into various energy sector scenarios.
