Pyrolobus fumarii is a species of archaea known for its ability to survive at extremely high temperatures that kill most organisms.
It was first discovered in 1997 in a black smoker hydrothermal vent at the Mid-Atlantic Ridge, setting the upper temperature threshold for known life to exist at 113°C.[1][2]
Strain 121, a microbe from the same family found at a vent in the Pacific Ocean, survived and multiplied during a 10-hours spent at 121°C in an autoclave. It was finally killed at a temperature of 130°C.[1]
