Thermococcus gammatolerans

Thermococcus gammatolerans is an archaea extremophile and the most radiation-resistant organism known to exist. Discovered in 2003 in a submarine hydrothermal vent in the Guaymas Basin about 2,000 m deep off the coast of California, Thermococcus gammatolerans thrives in temperatures between 55 and 95 °C with an optimum development around 88 °C. Its optimal growth pH is 6, favoring the presence of sulfur (S), which is reduced to hydrogen sulfide (H2S). It is the organism with the strongest known resistance to radiation, supporting a radiation of gamma rays from 30,000 gray (Gy).
