Answer 1

Filtration is the microbial control method that physically removes microbes without killing or inhibiting their growth, unlike other methods that directly affect the microbes.

Step-by-step explanation:

The microbial control method that does not kill microbes or inhibit their growth but instead physically removes them from samples is filtration. Methods like desiccation and lyophilization, which are drying processes, and nonionizing radiation, which alters microbial DNA, all affect the microbes directly.

In contrast, filtration acts by straining out microbes from liquids or air, thereby removing them without necessarily killing or inhibiting them.
