    Ein ressourcenschonendes und kostengünstiges Verfahren zur Herstellung von Bioplastik entwickeln Forscher am Karlsruher Institut für Technologie (KIT): In dem vom Bundesforschungsministerium geförderten Projekt „BioElectroPlast“ setzen sie Mikroorganismen ein, die aus Rauchgas, Luft sowie Strom aus erneuerbaren Quellen das Polymer Polyhydroxybuttersäure produzieren. Der so optimierte Prozess der mikrobiellen Elektrosynthese eröffnet für die Zukunft weitere Perspektiven, etwa zur Herstellung von Biokraftstoffen oder zur Speicherung von Strom aus regenerativen Quellen in Form chemischer Produkte.

  • Use of bacteria to produce valuable substances from carbon dioxide

    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.
