Goethe University Frankfurt coordinates European two million Euro project. Microbes are already used on a wide scale for the production of fuels and base chemicals, but for this most of them have to be “fed” with sugar. However, since sugar-based biotechnology finds itself in competition with food production, it is faced with increasingly fierce criticism. Carbon dioxide has meanwhile become the focus of attention as an alternative raw material for biotechnological processes. Goethe University Frankfurt has now taken charge of a collaborative European project, the aim of which is to advance the development of processes for microbial, CO2-based biotechnology. The project will be funded over the next three years with € 2 million.
