General Information: Petrotoga mobilis SJ95 (DSM 10674) is an anaerobic thermophile, isolated from the production waters of a North Sea oil reservoir. This organism, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Petroleum reservoirs are a unique subsurface environment characterized by high temperatures, moderate to high salt concentrations, and abundant organic matter.
