Question
Chapter 9, Problem 14CT
Summary Introduction
To answer:
The suitable membrane filters that separate bacteria from virus in the solution by a virologist.
Introduction:
Without any use of heat or chemicals, the microbes can be eliminated or controlled or stored by the means of filtration. The filters contain membranous sieves, which will entrap the microbes. The pore size of the filters will range from 0.2 µm to 2µm, which can also filter most of the viruses.

A patient comes into a hospital and has what appears to be an infection. Your microscope is broken so staining is not an option. Design an experiment to determine if the infection is caused by gram positive or gram negative bacteria.
The culture primarily contains nutrients such as sugars and a gel (agar). Why don’t viruses grow in a culture like bacteria do? Explain.
A virologist needs to remove all bacteria from a solution containing viruses without removing the viruses. What should the scientist do?
