Thermococcus profundus is a hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent. It is coccoid-shaped with 1–2 μm in diameter, designated as strain DT5432.[1]

One amylase isolated from T. profundus strain DT5432 was found to function at an optimal temperature of 80 °C. The scientists who extracted it speculate that it may have applications in the starch industry because of its heat tolerance and lack of any need for metal ions.[2]
