One alternative to autoclaving for sterilization of liquids is filtration. Imagine that you are using a filter to sterilize a dr
ug solution. You use a filter with a 0.22 \mum pore size. Which of the following microbes will effectively be removed by this filter? There are more than one answer possiblya. bacteria b. small virusesc. fungid. yeast
Both fungi and yeast will be effectively removed by a 0.22 micron pore size filter.
<em>The size of microscopic fungi ranges from 2 to 10 microns while the size of yeast ranges from 3 to 4 microns in diameter. Hence, both organisms will be effectively filtered off by a 0.22 micron filter paper.</em>
The size of bacteria ranges from 0.2 to 2 microns while that of virus is in nanometer. Hence both cannot be effectively removed by a 0.22 micron pore size filter paper.
