Answer:
Filtration
Step-by-step explanation:
Filtration is the process that reduces the microbes from a solution which consists of heat-sensitive substances. It is also used to produce sterilized solutions. Filtration is a process that physically removes the microbial population from the sample with the help of filters.
For example, the depth filters remove the microbes from the solution by trapping them to the filter material. Likewise, membrane filters are the porous membranes that are used to remove the vegetative cells of most of the microbes.
