Membrane Filtration An solution that is commonly applied, specifically in sterility testing, is neutralization by membrane filtration. This method relies upon the Bodily retention of your microorganism on the membrane filter, Using the antimicrobial agent passing with the filter in to the filtrate. The filter is then incubated for Restoration of feasible microorganisms. However, filtration by itself might not take away ample portions on the bactericidal agent to allow development of surviving microorganisms.
