Query: NC_014032:1408967 Salinibacter ruber M8 chromosome, complete genome
Lineage: Salinibacter ruber; Salinibacter; Rhodothermaceae; Bacteroidetes Order II; Bacteroidetes; Bacteria
General Information: Salinibacter ruber (strain M8) is a brightly red-pigmented, motile, rod-shaped, extremely halophilic Gram-negative bacterium isolated from a saltern crystallizer pond in Mallorca, Spain. It grows optimally at salt concentrations between 20 and 30% and does not grow below 15% salt. S. ruber is among the most halophilic organisms known within the domain Bacteria. This organism is an extremely halophilic aerobe originally isolated from saltern crystallizer ponds in Spain. These bacteria can coexist in significant colonies with halophilic archaea under saline conditions. In contrast to other bacteria they do not regulate their intracellular salt conditions through proton pumps, but instead their protein makeup has adapted to be functional under high ionic conditions.
Subject: NC_020134:2832857 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.
