WebMar 5, 2024 · 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. Pathogens are usually mesophiles. Thermophiles and hyperthemophiles are adapted to life at temperatures above 50 °C. WebMay 31, 2024 · What temperature do psychrophiles grow best? Bacteria that grow at temperatures in the range of -5 o C to 30 o C, with optimum temperatures between 10 o C and 20 o C, are called psychrophiles. These microbes have enzymes that catalyze best when the conditions are cold, and have cell membranes that remain fluid at these lower … haunted areas in indiana
