Query: NC_006371:1997954 Photobacterium profundum SS9 chromosome 2, complete sequence
Lineage: Photobacterium profundum; Photobacterium; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: Isolated at a depth of 2500 m from the Sulu Trough. High pressure tolerant bacterium. This bioluminescent genus was originally identified in 1878 in association with hake (a marine fish) in Cape Town, South Africa. This species was originally isolated from an amphipod homogenate enrichment from the Sulu Sea. It is a genetically tractable model system for studies of low temperature and high pressure adaptation, and has been used in studies of mono- and polyunsaturated fatty acid production under these conditions.
Subject: NC_020134:845164 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.
