For example, halophilic methanogens are potentially important microbes for carbon cycling in coastal wetland ecosystems but seem to be greatly understudied.
Organisms, like methanogens, in the archaea domain are extremophiles. For example, some archaea live in really hot temperatures, under.
Methanogens are microorganisms that produce methane as a by-product of their metabolism. Most methanogens are found in the gut of ruminants.
