C1-carbon sources for chemical and fuel production by microbial gas fermentation

- Autotrophic acetogens, carboxidotrophs, and methanotrophs can grow on CO, CO2 or CH4.
- Gas fermentation allows an economic production of commodity chemicals and biofuels.
- Anaerobic and aerobic processes using CO2, syngas (CO + H2) or CH4 are described.
- Microbial electrosynthesis coupled to CO2 reduction provides a novel approach.
- Industrial applications of microbial gas fermentation are presented.
