A gas fermentation is an industrial fermentation process that uses gaseous feedstock like methane, CO or CO₂ concerted by a living organism or enzyme to produce a specific product. Gas fermentation is requires organisms that are able to use these kind of feedstock as main or single carbon source for their metabolism.

Feedstock

For a gas fermentation gaseous carbon sources are used as a feedstock. They can be delivered from a gasification of biomass or other materials or directly be taken from a gas source like a biogas production or from an offgas point source.

Product

Products from a gas fermentation depend on the organism used and its specific metabolism. Examples can be different kinds of alcohols like ethanol, butanol or isobutanol, but also organic acids, proteins, hydrogen or bio-based polymers like polyhydroxyalcanoates (PHAs).
