Thermococcus chitonophagus Huber and Stetter 1996 |
Thermococcus chitonophagus is a chitin-degrading hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent. It is anaerobic, round to slightly irregular coccus-shaped, 1.2–2.5 μm in diameter and motile by means of a tuft of flagella.
Thermococcus chitonophagus is one of only three species of archaeon that can grow on chitin. The chitinase was isolated and found to have a molecular weight of 70 kDa. It retains 50% of its activity after an hour at 120 °C.
