Query: NC_009637:602079 Methanococcus maripaludis C7 chromosome, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Anaerobic methane-producing archeon. This strain was isolated from intertidal salt-marsh sediments. Methanococcus maripaludis is an obligately anaerobic, mesophilic, methane-producing archaeon. Growth on hydrogen and carbon dioxide results in the production of methane as a waste product. M. maripaludis stands out among methanogenic archaea as an ideal model species because of fast reproducible growth and effective genetic tools.
Subject: NC_014654:2101500 Halanaerobium sp. 'sapolanicus' chromosome, complete genome
Lineage: Halanaerobium hydrogeniformans; Halanaerobium; Halanaerobiaceae; Halanaerobiales; Firmicutes; Bacteria
General Information: Environment: Fresh water, Sediment; Temp: Mesophile; Temp: 34 - 42C. Organisms identified in the genus Halanaerobium (also known as Haloanaerobium) were first isolated from the Great Salt Lake in Utah, USA and have since been isolated from diverse saline environments such as oil reserviors, brine-seawater interfaces and hypersaline sediments. These bacteria are extremely salt-tolerant and are able to grow in concentrations of salt as high as 25%.
