Methanothermobacter are members of the domain Archaea, renowned for their methanogenic ability. They are hydrogenotrophic methanogens, which convert H2 + CO2 to methane 8. Growth occurs under strictly anaerobic conditions, whereby acetate may be assimilated or required by some species 8 9. Autotrophic growth is also possible by members of the genus 8. Methanothermobacter form natural syntrophic associations with bacteria including the genera Coprothermobacter 1 and Pelatomaculum 10 as examples. In pure culture cells appear as curved or crooked slender rods, which may occur singly, in pairs or as moderately long chains to filaments 8.
