5PY017 Pharmaceutical Microbiology Evaluation of antimicrobial effectiveness of disinfectants Abstract A control experiment was performed to rule out the effects of the medium and neutralizer to allow us to see the effect of the disinfectant on the four organisms within a 5 minute range. The bacterial suspension used for paired at different concentration data was Staphylococcus Aureus for which gave good results when the reduction factor value of 1.20x106 ml-1 was obtained for the organism
