Coprothermobacter proteolyticus DSM 5265

Coprothermobacter proteolyticus (strain ATCC 35245 / DSM 5265 / BT) is a rod-shaped, anaerobic, thermophilic proteolytic, Gram-positive bacterium isolated from a thermophilic digestor that was fermenting tannery wastes and cattle manure. This organism was originally classified as Thermobacteroides proteolyticus and subsequently assigned to the new genus of Coprothermobacter. C. proteolyticus has an optimum temperature for growth of 63 degrees Celsius. It is phylogenetically related (96.3 % sequence similarity) to Coprothermobacter platensis (a moderately thermophilic bacterium), and both show similar morphology and fermentation products. Both can reduce thiosulfate to sulfide with glucose as substrate. The thiosulfate addition clearly stimulates glucose utilization and growth. Anaerobic digestion is increasingly used for carbon decontamination of agroindustrial wastewaters. Proteins are frequently a major component of'such wastes, and their degradation, initiated by extracellular proteases, is often incomplete. The vast majority of full-scale digestors are mesophilic, however thermophilic treatment is also being explored as it may have advantages, especially for effluents produced at high temperature (adapted from PubMed 9828430).
