WebThermophiles produce some of the bright colors of Grand Prismatic Spring, Yellowstone National Park. 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 they can be bacteria or fungi. WebThe majority of psychrophilic bacteria are in the gram-negative genera Pseudomonas, Flavobacterium, Achromobacter, and Alcaligenes. Mesophilic bacteria are those in which optimum growth occurs between 20 and 45 °C (68 and 113 °F), although they usually can survive and grow in temperatures between 10 and 50 °C (50 and 122 °F).
