(meth-an'ō-jen),
Any methane-producing bacterium of the family Methanobacteriaceae.

methanogen

/meth·a·no·gen/ (meth´ah-nah-jen″) an anaerobic microorganism that grows in the presence of carbon dioxide and produces methane gas. Methanogens are found in the stomach of cows, in swamp mud, and in other environments in which oxygen is not present.

methanogen

(mə-thăn′ə-jən)
n.
Any of various anaerobic archaea that produce methane as a metabolic byproduct.

meth·an·o·gen

(meth-an'ō-jen)
Any methane-producing bacterium of the family Methanobacteriaceae.

methanogen

any BACTERIUM that can produce methane. The methanogens are found in the DOMAIN ARCHAEA, and form methane under anaerobic conditions, as an energy-yielding process.
