Answer:
D. Psychrophile
Explanation:
A psychrophile refers to the microorganism that can grow well at 0°C. These microbes have an optimum growth temperature of 15°C or lower. They can tolerate a temperature maximum of around 20°C but show inhibition of growth above that temperature. Some of the examples of psychrophile are <em>Bacillus psychrophilus, Chlamydomonas nivalis</em>. Psychrophiles are naturally found in Arctic and Antarctic habitats. According to the given information, the culture of the bacterial species was able to grow well at refrigeration and therefore, they are psychrophile.
