Detailed explanation-1: -Thermophilic bacteria are those that thrive within high temperatures, usually between 45 and 80 C (113 and 176F) and are found in environments such as hot springs, peat bogs, and near deep-sea hydrothermal vents. One type of “hyperthermophile", Methanopyrus kandleri, can even survive temperatures up to 122°C.
Detailed explanation-2: -They grow between 80 and 113 °C and represent the organisms at the upper temperature border of life. At ambient tem-peratures, although unable to grow, hyperthermophiles can survive for many years in a kind of “frozen” state.
Detailed explanation-3: -Examples of thermophilic microorganisms found in hot springs include bacteria in the genera Sulfolobus, which can grow at temperatures of up to 90 °C (194 °F), Hydrogenobacter, which grow optimally at temperatures of 85 °C (185 °F), and Thermocrinis, which grow optimally at temperatures of 80 °C (176 °F).
