The genus Caldicellulosiruptor contains the most thermophilic, plant biomass-degrading bacteria isolated to date. Previously, genome sequences from three cellulolytic members of this genus were reported (C. saccharolyticus, C. bescii, and C. obsidiansis). To further explore the physiological and biochemical basis for polysaccharide degradation within this genus, five additional genomes were sequenced: C. hydrothermalis, C. kristjanssonii, C. kronotskyensis, C. lactoaceticus, and C. owensensis. Taken together, the seven completed and one draft-phase Caldicellulosiruptor genomes suggest that, while central metabolism is highly conserved, significant differences in glycoside hydrolase inventories and numbers of carbohydrate transporters exist, a finding which likely relates to variability observed in plant biomass degradation capacity.
