Which category of bacteria thrives optimally at cold temperatures around 10°C, typical of refrigeration conditions?

Explanation

Psychrophilic bacteria are specialized to grow best at low temperatures, such as those found in refrigerators (around 10°C). Thermophilic bacteria prefer high temperatures, while mesophilic bacteria grow best at moderate temperatures. Therefore, cold-adapted (psychrophilic) bacteria are the ones that flourish under refrigeration conditions.
