Hydrogen-oxidising bacteria

Knallgas chemolithoautotrophs (e.g. Cupriavidus necator) that oxidise H2 to fix CO2 into microbial biomass for food and feed protein.

Where it's used

Gas fermentation of food protein
Microbial food protein grown by feeding hydrogen-oxidising bacteria a mix of hydrogen, CO2 and oxygen in gas-loop bioreactors — a land-free 'food from air' route now at commercial demonstration scale.
