Query: NC_015416:1872000 Methanosaeta concilii GP-6 chromosome, complete genome

Lineage: Methanosaeta concilii; Methanosaeta; Methanosaetaceae; Methanosarcinales; Euryarchaeota; Archaea

General Information: Methanosaeta, the predominant methane producer on earth, has received little attention in recent years due to its slow growth and difficulties in culturing. Therefore, the genome sequence is a valuable source of information about this microbe and offers the most tractable approach to understanding its physiology. Furthermore, the genome sequence of Methanosaeta concilii GP-6 significantly increases our knowledge of the role of acetate-utilizing methanoarchaea in the global carbon cycle, and also allows for a more complete comparative genomics analysis of methanogenic archaea as now both genera of aceticlastic methanoarchaea are now represented.

Subject: NC_003901:2906493 Methanosarcina mazei Go1, complete genome

Lineage: Methanosarcina mazei; Methanosarcina; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea

General Information: Methanosarcina mazei Go1 (DSM 3647) was isolated from an anaerobic sewage digester in Germany. Anaerobic methane-producing archeon. This organism is a strictly anaerobic, non-motile, methane-producing archaeon. This organism can also aggregate forming large irregular shaped clumps of cells. Occasionally these aggregates can grow to 1000 microns or more in diameter. Growth occurs at pH 5.5-8.0, with optimum growth at pH 6.8-7.2. Growth occurs at pH 5.5-8.0, with optimum growth at pH 6.8-7.2. Can be found in decaying leaf litter, garden soil, sewage treatment sludge digestors, black mud, feces of herbivores and other urban waste and sewage products.
