Detailed explanation-1: -Psychrophilic microorganisms have successfully colonized all permanently cold environments from the deep sea to mountain and polar regions. Some of these organisms, depending on their optimal growth temperature, are also known by the terms psychrotolerant or psychrotroph (Morita, 1975).

Detailed explanation-2: -Psychrophiles are extremophilic bacteria or archaea which are cold-loving having an optimal temperature for growth at about 15°C or lower, a maximal temperature for growth at about 20°C and a minimal temperature for growth at 0°C or lower.

Detailed explanation-3: -The psychrophiles are the cold lovers, with an optimum of 15oC or lower and a growth range of-20oC to 20oC. Most of these microbes are found in the oceans, where the temperature is often 5oC or colder. They can also be found in the Arctic and the Antarctic, living in ice wherever they can find pockets of liquid water.
