Thermococcus barophilus is a hyperthermophilic, anaerobic, mixed heterotrophic, and carboxydotrophic euryarchaeon isolated from the deep sea hydrothermal vent Snakepit site on the mid-Atlantic ridge at a depth of 3,550 m. T. barophilus is the first true piezophilic, hyperthermophilic archaeon isolated, having an optimal growth at 40 MPa. Here we report the complete genome sequence of strain MP, the type strain of T. barophilus. The genome data reveal a close proximity with Thermococcus sibiricus, another Thermococcus isolated from the deep biosphere and a possible connection to life in the depths.
巴氏深海热球菌是一种超嗜热、厌氧、混合异养和产羧基微生物,从大西洋中脊深海热液喷口蛇纹石区 3550 米深处分离得到。巴氏深海热球菌是第一个真正的嗜压高温古菌,最适生长压力为 40 MPa。本文报道了巴氏深海热球菌的模式菌株 MP 的全基因组序列。基因组数据表明其与从深海生物圈中分离得到的另一种嗜热古菌 Thermococcus sibiricus 密切相关,这可能与深海中的生命有关。
