General Information: Syntrophomonas wolfeisubsp. wolfei str. Goettingen (DSM 2245B) was isolated from anaerobic digestor sludge. Fatty acid-oxidizing bacterium. This organism is an anaerobic syntrophic fatty acid-oxidizing bacterium. It is the only bacterium known to produce energy from anaerobic degradation of saturated four to eight carbon fatty acids with protons serving as the electron acceptor. The cells have an unusual multilayered gram-negative cell wall. Syntrophomonas wolfei grows in coculture with Methanospirillum hungatei and can be isolated from anaerobic environments such as aquatic sediment or sewage digestor sludge.
