Detailed explanation-1: -Psychrophiles grow best in the temperature range of 0–15 °C whereas psychrotrophs thrive between 4°C and 25 °C. Mesophiles grow best at moderate temperatures in the range of 20 °C to about 45 °C.

Detailed explanation-2: -Temperature. Listeria monocytogenes is a psychrotrophic bacterium able to grow at refrigeration temperatures, although optimal growth occurs between 30 and 37°C.

Detailed explanation-3: -The term, psychrotroph (also termed psychrotolerant), was retained to denote organisms that have the ability to grow at low temperatures, but have their optimal and maximal growth temperatures above 15 and 20°C, respectively.

Detailed explanation-4: -Psychrotrophs: these species have an optimum growth temperature between 20 and 30ºC but can grow at 0 to 7º C. These play a major role in spoilage of refrigerated foods. mesophiles: include most bacteria, optimum growth temperature is 20-45°C.

Detailed explanation-5: -Psychrotolerant organisms, i.e. organisms that are capable of growth close to 0°C but with an optimum growth temperature of >20°C, have been isolated more often from permanently cold (<5°C) environments [2, 3] than psychrophilic organisms, which grow only at temperatures below 20°C [4].
