What type of bacteria thrives in colder temperatures ranging from 32 to 86 degrees?

Psychrophilic bacteria are specifically adapted to thrive in cold environments, typically between 32 to 86 degrees Fahrenheit. These bacteria have developed mechanisms that allow them to grow and metabolize at low temperatures, making them distinct from other types of bacteria.

Understanding the classifications of bacteria based on temperature preferences is essential for food safety and management. For example, mesophilic bacteria prefer moderate temperatures, usually between 68 to 113 degrees Fahrenheit, and are commonly associated with the temperatures found in the human body and many environmental settings. Thermophilic bacteria thrive at higher temperatures, often above 113 degrees Fahrenheit, and are typically found in hot environments such as hot springs or compost.

Acidophilic bacteria are not classified by temperature but rather by their preference for acidic environments. They grow best at a low pH, which does not directly pertain to temperature ranges.

This highlights the importance of recognizing psychrophilic bacteria in food safety, particularly in refrigeration and cold storage practices, where the control of bacterial growth is crucial to prevent foodborne illnesses.
