Question

Cultures of a bacterial strain were incubated in a refrigerator (5°c), on a lab bench (22°c), in a 37°c incubator, and in a 50°c incubator. after incubation, there was no growth at 37°c and 50°c, slight growth in the refrigerator, and abundant growth on the lab bench top. which term best describes this organism?

Answer 1

The term that best describes this organism is Psychrophile. Psychrophiles or cryophiles are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from -20 degrees to +10 degrees. They are found in places that are permanently cold, such as the polar regions and the deep sea. Falcultative psychrophile are organisms that grow slowly in the cold but have an optimum growth temp of 32 degrees .
