Detailed explanation-1: -Mesophilic bacteria and fungi experience optimal growth at temperatures of 25-40°C/77-104°F. Thermophilic, or heat-loving, microorganisms experience optimal growth at temperatures greater than 45°C/113°F and up to 100°C/212°F.
Detailed explanation-2: -Bacteria grow most rapidly in the range of temperatures between 40 ° and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” That’s why the Meat and Poultry Hotline advises consumers to never leave food out of refrigeration over 2 hours.
Detailed explanation-3: -PSYCHROPHILES grow best between-5oC and 20oC, MESOPHILES grow best between 20oC and 45oC and. THERMOPHILES grow best at temperatures above 45oC. THERMODURIC organisms can survive high temperatures but don’t grow well at such temperatures.
