Description and habitat

The species within Methanogenium are coccoid in shape and Gram-negatives and, like other methanogenic archaea, they produce methane from carbon dioxide, hydrogen or formate as substrates.^[2] Although they occasionally have flagella, they are non-motile. They are strictly anaerobic, and can be found in marine and lake sediments that lack oxygen.^[3]
