A gas fermentation process depends on microorganisms that are able to digest gaseous carbon sources. Best known for this ability are acetogenic bacteria using the Wood-Ljungdahl pathway or acetyl-CoA pathway to fix and convert CO/CO<sub>2</sub> and hydrogen to biomass and products. They are able to synthesize useful products such as ethanol, butanol and 2,3-butanediol and they are anaerobes so need to be used in an anaerobic, oxygen-free atmosphere, fermentation setting. For commercial applications, mainly strains from ''Clostridium ljungdahlii'' and ''C. autoethanogenum'' are used. | A gas fermentation process depends on microorganisms that are able to digest gaseous carbon sources.
