Comparative Study Of Disinfectant Efficiency Of Ethanol, Bleach And Phenolics Against Pseudomonas Aeruginosa And Staphylococcus Aureus

ABSTRACT Ethanol, Bleach and Phenolics are three kinds of disinfectants which have been widely used in common laboratories.  In this study, a compared experiment on these three disinfectants efficiency was conducted against Staphylococcus aureus and Pseudomonas aeruginosa using agar hole diffusion method.  Different concentrations of bleach (1%, 2%, 3%, 4% and 5%) were used on both organisms.  Also (50%, 60%, 70%, 85% and 95%) of ethanol as well as (5%, 10%, 20%, 25%, and 30%) Phenolics were used. Diffrences in  concentrations tested was because, the original concentrations of the disinfectan…
