Antibacterial Effectiveness of Disinfectants Used in Biology and Zoology Laboratory Working Tables

This study determined the bacterial effectiveness of disinfectants used in the science laboratories of Liceo de Cagayan University. Specifically, the study sought to know the antibacterial effectiveness of the disinfectants sodium hypochlorite, liquid detergent, and O-benzyl-p-chlorophenol by measuring the means of the zones of inhibition. It also compared the antibacterial effectiveness between liquid detergent and sodium hypochlorite, between O-benzyl-p-chlorophenol and Sodium hypochlorite, and between O-benzyl-p-chlorophenol and liquid detergent. Bacterial samples tested were isolated from six laboratory working tables. The bacterial isolates were then subjected to susceptibility assay for the determination of the zones of inhibition. Sodium hypochlorite, liquid detergent, and O-benzyl-p-chlorophenol had shown the antibacterial property. Sodium hypochlorite was as effective as the liquid detergent. Moreover, O-benzyl-p-chlorophenol is more effective than sodium hypochlorite and liquid detergent. Among the disinfectants tested, O-benzyl-p-chlorophenol appeared to be the most effective.
