Cultures of a bacterial species were incubated on the shelf of a refrigerator, out on a lab bench top, on the shelf of a 37° C incubator and on the shelf of a 50° C incubator. After incubation, there was no growth at 37° C and 50° C, slight growth out on the bench top and abundant growth at refrigeration. What term could be used for this species?

The correct term to be used for this specie is; Psychrophiles

Explanation:

Psychrophiles are extremophilic organisms that are capable of growth and reproduction in low temperatures ranging from -20°C to +10°C. they are found in places that are permanently cold, such as the polar regions and the deep sea. they can be contrasted with thermophiles hwhich are organisms that thrive at unusually high temperatures psychrophile is greek for "cold loving". many such organisms are bacteria or archae but some eukaryotes such as lichen, sonw algae, fungi and wingless midges are also classified as psychrophiles.
