Passage
Bacteria can be categorized by how they respond, as indicated by reproduction and growth, to certain temperatures.
They are grouped into four categories—psychrophiles, psychrotrophs, mesophiles, and thermophiles—based on their growth response to certain temperatures. Minimal growth temperature is the lowest point at which the bacteria will reproduce. Optimum growth point is the temperature at which the bacteria reproduce most efficiently. Maximum growth point is the very highest temperature to which the bacteria will respond, beyond which the bacteria will not reproduce at all. Table 1 lists the types of bacteria as well as the growth points for each.
Table 2 represents a list of common bacteria and their growth points.

Q. A new bacteria was discovered by scientists. It reproduces best at 55 C and does not show any new growth if exposed to temperatures above 65 C. This bacteria can most likely be categorized as a:
  • a)
    psychrophile.
  • b)
    psychrotroph.
  • c)
    mesotroph.
  • d)
    thermophile.
Correct answer is option 'D'. Can you explain this answer?

The best answer is d. Thermophiles are shown by Table 2 to reproduce best, that is to have an optimum growth point, between 50 and 60C.
A bacteria that reproduces at 55 C would likely be classified there. Further, if the bacterium does not show any new growth above 65 C, that also fits within the range of maximum growth points for thermophiles of between 60 and 90 C.
