Methane production, or methanogenesis, is the only biochemical pathway for ATP generation in methanogens. All known methanogens belong exclusively to the domain Archaea, although some bacteria, plants, and animal cells are also known to produce methane. [1]
Organisms capable of producing methane for energy conservation have been identified only from the domain Archaea, a group phylogenetically distinct from both eukaryotes and bacteria, although many live in close association with anaerobic bacteria. The production of methane is an important and widespread form of microbial metabolism.
Aerobic methane production is a potential biological pathway for atmospheric methane (CH 4) production under ... of DMSP by bacteria results in the release of methane.
They are bacteria or archaea, can grow aerobically or anaerobically, and require single-carbon compounds to survive. Methanotrophs are especially common in or near environments where methane is produced, although some methanotrophs can oxidize atmospheric methane. Their habitats include wetlands, soils, marshes, rice paddies, landfills, aquatic ...
In a process called acetoclastic methanogenesis, microorganisms from the classification domain archaea produce methane by fermenting acetate and H 2-CO 2 into methane and carbon dioxide. H 3 C-COOH → CH 4 + CO 2. Depending on the wetland and type of archaea, hydrogenotrophic methanogenesis, another process that yields methane, can also occur ...
An example of hydrogenotrophy is performed by carbon dioxide-reducing organisms [1] which use CO 2 and H 2 to produce methane (CH 4) by the following reaction: CO 2 + 4H 2 → CH 4 + 2H 2 O; Other hydrogenotrophic metabolic pathways include acetogenesis, sulfate reduction, and other hydrogen oxidizing bacteria.
CO 2 + 4 H 2 → CH 4 + 2 H 2 O. The final step in the process is catalyzed by the enzyme methyl coenzyme M reductase (MCR).

Methanosarcina acetivorans is a versatile methane producing microbe which is found in such diverse environments as oil wells, trash dumps, deep-sea hydrothermal vents, and oxygen-depleted sediments beneath kelp beds.
