Methanogens are the group or genus of archaea that are part of the microbiota of the human colon, vagina, and mouth.
<h3>Methanogens:</h3>
Methanogens are microorganisms that produce methane as a byproduct of their metabolism. They are frequently found in anaerobic sludge during the treatment of sewage. The rumen also contains these bacteria (a part of the stomach of cattle). A methanobacterium is an example.
The majority of the methane in the gut is produced by methanogenic archaea after colonization by converting carbon dioxide into methane in the presence of hydrogen.
The human gastrointestinal system contains methanogens (also known as methanogenic archaea). It is well recognized that microbial interactions with the host have physiological and biochemical effects that can either be good or bad.
