Query: NC_017068:2604876 Selenomonas ruminantium subsp. lactilytica TAM6421, complete
Lineage: Selenomonas ruminantium; Selenomonas; Veillonellaceae; Selenomonadales; Firmicutes; Bacteria
General Information: This organism is a member of the normal flora of the sheep rumen. The genus Selenomonas constitutes a group of motile crescent-shaped bacteria and includes species living in the gastrointestinal tracts of animals, in particular, the Ruminants. Despite being Firmicutes they stain Gram-negative and possess a double bilayer. Cells are crescent or bean-shaped with coiled flagella located on the concave surface with an infolding of the cell membrane behind the flagellar attachment point.
Subject: NC_020134:1173000 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.
