Depending on temperature, bacteria can be classified as: Psychrophiles; Psychrophiles are extremophilic cold-loving bacteria or archaea with an optimal temperature for growth at about 15 °C or lower (maximal temperature for growth at 20 °C, minimal temperature for growth at 0 °C or lower). Psychrophiles are typically found in Earth's ...
A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from 20 to 45 °C (68 to 113 °F). [1] The optimum growth temperature for these organisms is 37 °C (about 99 °F). [2] The term is mainly applied to microorganisms.
A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). [1] [2] Many thermophiles are archaea, though some of them are bacteria and fungi. Thermophilic eubacteria are suggested to have been among the earliest bacteria. [3]
The bacterium is extremely thermophilic, with an optimal growth temperature of about 65 °C (149 °F). Thermus thermophilus was originally isolated from a thermal vent within a hot spring in Izu, Japan by Tairo Oshima and Kazutomo Imahori. [1]
The current record growth temperature is 122 °C, for Methanopyrus kandleri. Although no hyperthermophile has shown to thrive at temperatures >122 °C, their existence is possible. Strain 121 survives 130 °C for two hours, but was not able to reproduce until it had been transferred into a fresh growth medium, at a relatively cooler 103 °C.
S. thermophilus has an optimal growth temperature range of 35–42 °C (95–108 °F), ... The bacteria breaks down lactose, the sugar in milk, ...
Climate change is causing the rapid growth of an organism that can cause illness or even death in humans, finds a new study. Alarming growth of deadly bacteria in oceans linked to warming temperatures
The danger zone is the temperature range in which food-borne bacteria can grow. Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C).
