Pyrococcus horikoshii is a hyperthermophilic, anaerobic archaeon, first isolated from hydrothermal fluid samples obtained at the Okinawa Trough vents at a depth of 1,395 metres (4,577 ft). It is obligately heterotrophic, cells are irregular cocci with a tuft of flagella, growing optimally at 98 °C, sulphur greatly enhancing its growth.[1]
