What range of temperatures do mesophilic microorganisms typically thrive in?

• A. Below 32°F
• B. 32°F to 68°F
• C. 68°F to 113°F
• D. Above 133°F

Answer: (C)

Mesophilic microorganisms are those that thrive in moderate temperature conditions, and they typically grow best within the range of 68°F to 113°F (about 20°C to 45°C). This temperature range is conducive to their metabolic processes and growth, making it optimal for many bacteria, fungi, and other microorganisms found in environments like soil, human bodies, and various food products. Temperatures below 32°F would be too cold for mesophiles, leading them to enter a dormant state. Similarly, the range from 32°F to 68°F is often associated with psychrophilic organisms, which prefer cooler environments. Temperatures above 113°F could be too extreme for mesophiles, as many would be inactivated or killed at such high temperatures, commonly associated with thermophilic microorganisms that thrive in hot springs or composting processes. Understanding the preferred temperature range for mesophilic organisms is crucial, especially in settings like food safety, where their growth can lead to spoilage or foodborne illnesses.
