Biogas is an attractive renewable energy carrier. However, it contains CO2 which limits its use for certain applications. Here we report a novel approach for removing CO2 from biogas and capturing it as a biochemical through a biological process. This approach entails converting CO2 into biosuccinic acid using the bacterial strain Actinobacillus succinogenes 130 Z, and simultaneously producing ...

High cell densities were obtained by separating the cells with an external hollow fibre filter. Extreme product inhibition at high succinate titres resulted in cell death and subsequent lysis. Accordingly, the highest succinate titre obtained during continuous fermentation was 25 g.L at a dilution rate of 0.05 h. The highest volumetric productivity of 3 g.L.h and the highest succinate yield (0....
