Lineage: Methanosalsum zhilinae; Methanosalsum; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: Environment: Fresh water, Sediment; Isolation: Sediment of alkaline lake; Temp: Mesophile; Country: Egypt: Wadi el Natrun. Methanosalsum zhilinae was first isolated from an alkaline, saline lake sediment. This organism uses trimethylamine and methanol for growth and methanogenesis.
Subject: NC_015416:2292555 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.
