Query: NC_020134:2295092 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.

Subject: NC_014328:1 Clostridium ljungdahlii ATCC 49587 chromosome, complete genome

Lineage: Clostridium ljungdahlii; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria

General Information: This strain was isolated from chicken yard waste and is studied for its ability to produce ethanol. This acetogenic species has the ability to convert carbon monoxide into ethanol. The yield of this process has been increased substantially in the laboratory by using a dual-fermentation system. A methanogenic conversion step has also been designed for utilizing some of the waste products generated during the synthetic process.
