A methanogen pertains to any of the various archaeabacteria that are capable of producing methane through the process of methanogenesis. Methanogenesis is the production of methane as a part of the metabolism in methanogens.

Professor Lee Krumholz explains everything you need to know about methane, including his research on the methane oxidizing bacteria that could have tremendous impact on energy production and the environment. Lee Krumholz is an environmental microbiologist at the University of Oklahoma where he teaches Geomicrobiology and other microbial ecology related courses and labs. His research focuses on how bacteria survive and grow in several different natural ecosystems.

Methanogenesis, which yields the least amount of energy, takes place in the most extreme (reduced) anaerobic conditions. Methanogens carry out methanogenesis which produces methane (CH4), a potent greenhouse gas.
