Definition of Thermophilic

Thermophilic is the ability of the organisms to withstand and tolerate high temperatures. It is derived from the Greek word’s thermos meaning heat and philia meaning love. The temperature ranges from 40 to 122 degrees Celsius. Only thermophiles have the characteristics of withstanding this much high temperature. If any other bacterium is exposed to such a temperature, it would get damaged or killed.


There are three types of thermophiles depending upon their optimal growth temperatures namely simple thermophiles, extreme thermophiles, and hyperthermophiles. Thermophiles are classified as facultative thermophiles, obligate thermophiles, and hyperthermophiles. Thermophiles are known to be found in the geothermal regions of the earth such as hot springs etc.
