Names Caldicellulosiruptor kronotskyensis 2002
Accession numbers NC_014720
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 kronotskyensis (strain DSM 18902 / VKM B-2412 / 2002 is a strictly anaerobic, cellulolytic, non-spore-forming, extremely thermophilic, Gram-positive bacterium isolated from a terrestrial neutral geothermal spring in Geyser Valley in the Kronotsky National Park, region of Kamchatka (Far East, Russia). Cells are short, straight rods (3-3.2 x 0.5-0.7 mm) with flagella. Temperature range for growth is between 45-82 degrees Celsius, with optimum growth at 70 degrees Celsius. The pH range for growth is between 6.0-8.0, with optimum growth at pH 7.0. It is a chemo-organoheterotroph which is capable of fermenting a wide spectrum of carbohydrates (cellulose, starch, xylan, dextran, pectin, cellobiose, glucose, fructose, sucrose, xylose, maltose, galactose, lactose, arabinose, mannitol and yeast extract). It does not grow with pyruvate, chitin, raffinose, trehalose, ribose or peptone. (Adapted from PMID: 21216991 and 18523201). (EBI Integr8)
