Which of the following microbial control methods does not actually kill microbes or inhibit their growth but instead removes them physically from samples?
A
Filtration.
B
Desiccation.
C
Lyophilization.
D
Non-Ionizing Radiation.
Verified step by step guidance1
Understand the concept of microbial control methods: These are techniques used to eliminate or reduce the number of microorganisms in a given environment.
Identify the method that physically removes microbes: Filtration is a process that separates particles from fluids by passing the fluid through a filter, which traps the particles.
Differentiate between killing/inhibiting and removing: Killing or inhibiting involves destroying or stopping the growth of microbes, while removing involves physically separating them from the sample.
Examine the options: Filtration, Desiccation, Lyophilization, and Non-Ionizing Radiation. Determine which method involves physical removal.
Conclude that filtration is the method that physically removes microbes without killing or inhibiting their growth.
