Question

One alternative to autoclaving for sterilization of liquids is filtration. Imagine that you are using a filter to sterilize a drug solution. You use a filter with a 0.22 μm pore size that traps cells. Which of the following microbes will effectively be removed by this filter? Select all that apply. View Available Hint(s) Select all that apply. small viruses yeast E. coli fungi

Answer 1

Yeast, fungi, and E. coli.

Step-by-step explanation:

Filter with a 0.22 μm size will filter out the drug solution and remove effectively yeast, fungi and E. coli but it can not remove effectively the small viruses because the size of small viruses are in nano meter while the filter pore size is 0.22 μm.

So, virus will not remove effectively from filter while yeast size is 3 - 4 μm, fungi size is 2 - 10 μm which can remove easily.
