Methanosarcina acetivorans is a versatile methane producing microbe which is found in such diverse environments as oil wells trash dumps deep-sea hydrothermal vents and oxygen-depleted sediments beneath kelp beds. Only M. acetivorans and microbes in the genus Methanosarcina use all three known metabolic pathways for methanogenesis. Methanosarcinides including M. acetivorans are also the only archaea capable of forming multicellular colonies and even show cellular differentiation.
