Query: NC_009464:225400 Uncultured methanogenic archaeon RC-I, complete genome
Lineage: Methanocella arvoryzae; Methanocella; Methanocellaceae; Methanocellales; Euryarchaeota; Archaea
General Information: This organism is a key methane producer in the rhizome of rice. A large portion of the methane that is emitted in rice fields is produced by methanogenic archaea. Rice Cluster I (RC-I) methanogens in the rice rhizosphere play a key role in this methane production.
Subject: NC_007355:499764 Methanosarcina barkeri str. fusaro chromosome 1, complete sequence
Lineage: Methanosarcina barkeri; Methanosarcina; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: Methanosarcina barkeri strain Fusaro was isolated from mud samples taken from the freshwater lake, Lago del Fusaro near Naples, Italy. This organism is a strictly anaerobic, non-motile, methane-producing archaeon and has been found in marine mud, rumens of ungulates, lagoons polluted with animal waste and sludge from anaerobic sewage digestors.
