Psychrotolerant Microorganisms Can Survive and Grow At

Question

Psychrotolerant microorganisms can survive and grow at
A) refrigeration temperatures.
B) boiling temperatures.
C) extreme fluctuations in water availability.
D) high salt or sugar concentrations.

Accepted Answer

Psychrotolerant microorganisms can survive and grow at refrigeration temperatures, which are typically between 0-7°C (32-45°F). They are able to tolerate these cooler temperatures, but still have an optimal growth temperature range that is higher. They are not able to survive or grow at boiling temperatures, extreme fluctuations in water availability, or high salt or sugar concentrations.
