Query: NC_010003:2029416 Petrotoga mobilis SJ95, complete genome Lineage: Petrotoga mobilis; Petrotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria 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.

General Information: Nitrogen fixation. Thermophilic strictly anaerobic bacterium oxidizing acetate to CO2 in syntrophic association with a methanogenic partner. Capable of growing with various substrates such as alcohols and methylated nitrogen compounds, and to reduce sulfate in the presence of acetate. Isolated from sludge of an anaerobic digester run at 58 degrees C. Thermacetogenium phaeum is a strictly anaerobic, homoacetogenic bacterium. It is exceptional because it can use the homoacetogenic Wood-Ljungdahl (CO- dehydrogenase) pathway both for acetate formation and acetate oxidation. Acetate oxidation is possible only in syntrophic cooperation with a methanogenic partner which maintains a low hydrogen and/or formate concentration in the coculture. With this, the bacterium operates close to the thermodynamic equilibrium of substrate conversion, similar to other syntrophically fermenting bacteria such as Syntrophomonas wolfei the genomes of which have been sequenced as well in the recent past.
