WebPsychrophiles. The psychrophiles are the cold lovers, with an optimum of 15 o C or lower and a growth range of -20 o C to 20 o C. Most of these microbes are found in the oceans, where the temperature is often 5 o C or colder. They can also be found in the Arctic and the Antarctic, living in ice wherever they can find pockets of liquid water.
