These organisms are obligate anaerobes (can live without oxygen) and extremophiles (resist extreme conditions). . 480 lessons. Sometimes they are found in the intestinal tracts of ruminants. Extreme thermophiles thrive in very hot environments, extreme halophiles thrive in highly saline environments, and methanogens are named for the unique way they obtain energy: They use carbon dioxide to oxidize hydrogen, releasing methane as a waste product. . Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use.Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Methanosarcinales: They are found in freshwater, marine environments, and extremely halophilic sediments as well as in anaerobic sludge digesters and the gastrointestinal tracts of animals. That is the way they produce their energy. The methanogenic and methanotrophic archaea are found abundantly in the Antarctic habitats.

However, they are living beings with genetic and metabolic characteristics that are closer to eukaryotic organisms, although their evolutionary path is completely different. Let's look at some specific types of methanogens and their habitats. Methanogens, under anoxic conditions take substrates like carbon dioxide, hydrogen, and organic matter to produce methane by the methanogenesis process. This organism inhabits hydrothermal vents on the ocean floor and was first discovered in the Gulf of California at a depth of 2000m at temperatures of 84-100 degrees Celsius. Other extremophiles like halophiles (salt-loving) and acidophiles (acid-loving) are members of the Archaea Domain. Because thermophiles like hot temperatures, they are found in some of the most hostile environments on Earth.
