Question

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?

Answer 1

Answer:

This species are sychrofiles .

Explanation:

Bacteria can be classified according to their optimal growing temperature in:

• sychrofiles  (like cold temperatures; examples: species that live in cold water from Antarctica )

• mesophylls  (like moderate temperatures; species that live in the ground of a caribbean country )

• thermophiles (like high temperatures; for example, a bacteria that lives in thermal waters)
