Bioplastikproduktion mithilfe eines extremophilen kathodischen Biofilms

As the atmospheric CO2 concentrations are increasing, its usage as biotechnological substrate becomes a focus area of applied scientists. As a rather new technique to energize the process of CO2 fixation, microbial electrosynthesis offers the advantage to establish continuous processes based on a cathodic biofilm that is supplied with electrical energy provided by renewable resources. Here we present the cathodic biofilm growth of Kyrpidia spormannii, a recently isolated thermophilic organism that is naturally capable of producing the biodegradable biopolymer polyhydroxybutyrate (PHB).
