Methanothermococcus okinawensis

Methanothermococcus okinawensis is a thermophilic, methane-producing archaeon first isolated from deep-sea hydrothermal vent on the western Pacific Ocean. Its cells are highly motile, irregular cocci, with a polar bundle of flagella. Its type strain is IH1T (=JCM 11175T =DSM 14208T).[1] It grows at an optimal temperature of 60–65 °C and pH of 6.7. It is strictly anaerobic and reduces carbon dioxide with hydrogen to produce methane, but it can also use formate.[1] Research studies indicate that it might be able to survive extreme conditions in solar system's other bodies, such as Saturn's moon Enceladus.[2]
