Caldicellulosiruptor owensensis OL

Names Caldicellulosiruptor owensensis OL
Accession numbers NC_014657
Background Cellulolytic capability is widely distributed across the domain bacteria and extremely thermophilic cellulose-degrading microorganisms are of particular fundamental and biotechnological interest owing to the presence of highly thermostable enzymes. Caldicellulosiruptor owensensis (strain ATCC 700167 / DSM 13100 / OL) is a strictly anaerobic, cellulolytic, non-spore-forming, extremely thermophilic, Gram-positive bacterium isolated from a sediment sample taken from Owens Lake, California. Cells are short rods which sometimes formed long chains containing a few coccoid cells. It grows at temperature between 50-80 degrees Celsius, with an optimum at 75 degrees Celsius. The pH range for growth is between 5.5-9.0 with an optimum at about pH 7.5. When grown on glucose at optimal conditions, its doubling time is 7-3 h. In addition to glucose, C. owensensis utilized sucrose, xylose, fructose, ribose, xylan, starch, pectin and cellulose. Yeast extract stimulates growth on carbohydrates but is not obligately required. The end products from glucose fermentation are lactate, acetate, ethanol, H, and CO. (Adapted from PMID: 21216991 and 9542080). (EBI Integr8)
