Query: NC_008346:410940 Syntrophomonas wolfei subsp. wolfei str. Goettingen, complete
Lineage: Syntrophomonas wolfei; Syntrophomonas; Syntrophomonadaceae; Clostridiales; Firmicutes; Bacteria
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.
Subject: NC_020134:2948000 Clostridium stercorarium subsp. stercorarium DSM 8532, complete
Lineage: Clostridium stercorarium; Clostridium; unclassified Ruminococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Lignocellulosic biomass has great potential as an abundant and renewable source of fermentable sugars through enzymic saccharification. Clostridium stercorarium is a catabolically versatile bacterium producing a wide range of hydrolases for degradation of biomass. Together with Clostridium thermocellum, Clostridium aldrichii and other cellulose degraders, it forms group I of the clostridia. It is moderately thermophilic, with an optimum growth temperature of 65 degrees C, and has repeatedly been isolated from self-heated compost. The two-component cellulase system of C. stercorarium has been investigated thoroughly. Due to its ability to utilize the various polysaccharides present in biomass it is especially suited for the fermentation of hemicellulose to organic solvents. Some isolates have been used in Japan in a single-step ethanol-fermenting pilot-process with lignocellulosic biomass as substrate.
