Genus-specific remodeling of carbon and energy metabolism facilitates acetoclastic methanogenesis in Methanosarcina spp. and Methanothrix spp. [PDF]
Journal of BacteriologyMethanogenic archaea (methanogens) are microorganisms that obligately produce methane as a byproduct of their energy metabolism. While most methanogens grow on CO2+H2, isolates of the genera Methanosarcina and Methanothrix can use acetate as the sole ...

Putative Extracellular Electron Transfer in Methanogenic Archaea
Frontiers in Microbiology, 2021 It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.
