Query: NC_009051:2365711 Methanoculleus marisnigri JR1, complete genome
Lineage: Methanoculleus marisnigri; Methanoculleus; Methanomicrobiaceae; Methanomicrobiales; Euryarchaeota; Archaea
General Information: Methanogen present in marine and freshwater sediments. Methanoculleus marisnigri was first isolated from sediment from the Black Sea, but has also been identified in freshwater sediments. This organism can use hydrogen, formate, and secondary alcohols, such as propanol and butanol, for methanogenesis.
Subject: NC_013665:849508 Methanocella paludicola SANAE, complete genome
Lineage: Methanocella paludicola; Methanocella; Methanocellaceae; Methanocellales; Euryarchaeota; Archaea
General Information: This strain was isolated in Japan from rice paddy samples. Strain SANAE belongs to the Rice Cluster I (RC-I), a 16S rRNA and mcrA gene sequences-defined euryarchaeal lineage within Methanosarcinales and Methanomicrobiales. The RC-I group plays a key role in releasing methane from rice fields, which accounts for 10 to 25% of the global methane emissions.
