A hyperthermophile is an organism that thrives in extremely hot environments—from 60 °C (140 °F) upwards. An optimal temperature for the existence of hyperthermophiles is above 80 °C (176 °F). Hyperthermophiles are a subset of extremophiles, which are often micro-organisms within the domain Archaea, although some bacteria are able to tolerate temperatures of around 100 °C (212 °F), as well – Wikipedia.

Sulfolobus acidocaldarius, both a hyperthermophile and an acidophile, was found in the late 1960s in a hot, acidic spring in Yellowstone National Park, Wyoming. It was the first hyperthermophile to be identified in the scientific history. It was found to grow optimally between 75 and 80 °C, with pH optimum in the range of 2-3.

The Aquifex genus of bacteria  has been found living in hot sprigs in Yellowstone National Park, where temperatures can reach 205 degrees Fahrenheit (96 degrees Celsius).

However, scientists thought that it is unlikely for microbes to survive at temperatures above 150 °C, as the cohesion of DNA and other vital molecules begins to break down at this point.

  1. Is there a difference between hyperthermophiles and thermophiles? Is it that one can exist at a greater temperature than the other. Also I never thought of an organism being two kinds of extremophiles for some reason, that is so cool!


    1. Hyperthermophile is a derived term of thermophile. Hyperthermophile is an organism that lives and thrives in an extremely hot environment! And the temperature in which thermophile can live and thrive is just relatively high.
