Hydrogenotroph
Hydrogenotrophs are
.An example of hydrogenotrophy is performed by carbon dioxide-reducing organisms[1] which use CO2 and H2 to produce methane (CH4) by the following reaction:
- CO2 + 4H2 → CH4 + 2H2O
Other hydrogenotrophic metabolic pathways include
Background Information
Hydrogenotrophic bacteria were first experimented with by NASA in the 1960s in order to find a replenishable food source.[4] Hydrogenotrophic bacteria have been found to have a high protein and carbohydrate content and have been a guiding principle in developing sustainable agricultural methods.[citation needed] Experimentation has revealed that hydrogenotrophic bacteria can convert carbon dioxide into food more rapidly than plants, making them an efficient and sustainable alternative to implement into plant-based high-protein diets and as a substitute in products that use plant extracts and oils.[5]
Hydrogenotrophs are commonly found in the human gut, along with other fermentative bacteria which live in symbiosis with one another.[4] They are also found in soils and in sediments of freshwater and marine ecosystems around the world.[6]
