Methanogenic organisms
WebAnaerobic methanogenic archaea are largely responsible for methane production, while aerobic methanotrophic bacteria, as well as anaerobic methanotrophic bacteria and archaea, are involved in methane oxidation. In anoxic wetland soils, methanogens produce methane, while methanotrophs act as a filter and reduce methane emissions. Webtransfer in methanogenic propionate degrading consortia.
