Query: NC_000853:771746 Thermotoga maritima MSB8, complete genome
Lineage: Thermotoga maritima; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Rod-shaped thermophilic marine bacterium that metabolizes many simple and complex carbohydrates including glucose, sucrose, starch, cellulose, and xylan. This hyperthermophilic organism was originally isolated from a geothermal marine area near Vulcano, Italy. Thermotoga maritima is a hyperthermophile with an optimum growth temperature of 80 degrees C. This organism, a member of the Thermotogales, has the characteristic sheath-like envelope which extends beyond the cell wall. These organisms are heterotrophs are able to use a wide range of carbohydrates.
Subject: NC_020134:2772500 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.
