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 or cryophiles (adj. psychrophilic or cryophilic) are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from −20 °C (−4 °F) to 20 °C (68 °F). They have an optimal growth temperature at 15 °C (59 °F).
Detailed explanation-3: -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.
