Thermophilic organisms are microorganisms which are capable of tolerating and growing in very hot temperatures where other microorganisms may not survive.

  • Athermophileis an organism — a type ofextremophile— that thrives at relatively high temperatures, between 45 and 122 C (113and 252F).Many thermophiles arearchaea. Thermophiliceubacteriaare suggested to have been among the earliest bacteria.

    Thermophiles are found in variousgeothermallyheated regions of theEarth, such as hot springs like those inYellowstone National Park(see image) anddeep seahydrothermal vents, as well as decaying plant matter, such as peat bogs and compost.

    Unlike other types of bacteria, thermophiles can survive at much hotter temperatures, where as other bacteria would be damaged and sometimes killed if exposed to the same temperatures.

    As a prerequisite for their survival, thermophiles containenzymesthat can function at high temperatures. Some of these enzymes are used inmolecular biology(for example, heat-stableDNA polymerasesforPCR), and in washing agents.

    "Thermophile" is derived from theGreek:θερμÏŒτητα(thermotita), meaning heat, andGreek:φÎλια(philia), love.
