Methanococcus aeolicus is a methanogenic archaeon in the order Methanococcales, capable of producing methane through the reduction of carbon dioxide with hydrogen. It inhabits marine sediments and hydrothermal environments where it contributes to anaerobic carbon cycling. Like other members of the genus, it is strictly anaerobic and mesophilic to slightly thermophilic.

Methanococcus maripaludis is a mesophilic, hydrogenotrophic methanogenic archaeon in the family Methanococcaceae, isolated from salt marsh sediments. It has become an important model organism for studying methanogenesis, archaeal metabolism, and gene regulation due to well-developed genetic tools available for this species. It produces methane by reducing carbon dioxide with hydrogen under strictly anaerobic conditions.
