Detailed explanation-1: -Psychrophilic and psychrotrophic microorganisms have the ability to grow at 0 degree C. Psychrotrophic microorganisms have a maximum temperature for growth above 20 degrees C and are widespread in natural environments and in foods.

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: -Organisms that inhabit cold environments have been subdivided into psychrophiles sensu stricto, which grow optimally at less than 15°C (upper limit of 20°C), and psychrotolerant organisms, which survive at temperatures below 0°C but grow optimally at 20–25°C 6.

Detailed explanation-4: -Psychrophiles. 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.

Detailed explanation-5: -Obligate psychrophiles, which have been isolated from Arctic and Antarctic ocean waters and sediments, have optimum growth temperatures of about 10 °C (50 °F) and do not survive if exposed to 20 °C (68 °F).
