A new archaeal isolate has been reported that is capable of growing at up to 121 degrees C. The hyperthermophile, dubbed strain 121, grows chemoautotrophically using formate as an electron donor and FeIII as an electron acceptor and is closely related to members of the archaeal genera Pyrodictium and Pyrobaculum. Although the reported maximum growth temperature of strain 121 is 8 degrees C higher than the previous record holder (Pyrolobus fumarii; Tmax = 113 degrees C), the two organisms have virtually the same optimal growth temperatures.

生命的最高温度-我们在哪里划清界限？

已经报道了一种新的古细菌分离物，其能够在高达121摄氏度的温度下生长。被称为菌株121的超嗜热菌通过甲酸盐作为电子供体和FeIII作为电子受体进行化学自养生长，并且与古细菌属成员密切相关。烈火和焦炭。尽管报告的菌株121的最大生长温度比以前的记录保存者（Pyrolobus fumarii； Tmax = 113摄氏度）高8摄氏度，但这两种生物的最佳生长温度几乎相同。
