The unique innovation in “TRANSFORMATE” is the full integration and optimization of a two-stage process (electrolysis and fermentation) for the direct conversion of CO2 into biopolymers via formic acid. For the first time, a formic acid electrolyzer is coupled to a bioreactor and the interaction of the integrated system will be optimized. In a first step, CO2 is reduced by electrochemical conversion to formic acid. In a second step, the formic acid is fed into a bioreactor, where formic acid metabolizing microorganisms (formatotrophs) convert the feedstock formic acid into specialty chemicals at very high selectivity.
