B) membrane filtration.
C) freezing.
D) lyophilization.
E) refrigeration.

Question

Quizplus · Accepted Answer

Membrane filtration is the most appropriate option to sterilize liquid media containing heat-sensitive components. This method involves passing the liquid through a filter with pores small enough to trap microorganisms but large enough to allow the liquid to pass through. It is effective in removing bacteria and viruses, making it a suitable alternative to heat sterilization methods. UV light, freezing, lyophilization, and refrigeration are not effective methods for sterilizing liquid media.
