Study of the Inhibitory Activity of Acetic Acid Compared with Dettol Solution in Sterilizing Study Seats

Abstract

The study included the collection of 40 different samples of study seats in the Department of Biology, University of Anbar. The results showed that the seats contaminated with six different types of bacteria, Pseudomonas SSP occupied the highest percentage was 44% (56 isolates), followed by Escherichia coli, 25% (32 isolates), Bacillus SPP recorded 17% (13) isolates, while Klebsiella SPP and Staphylococcus aureus showed 9% and 5% (12 and 6 isolates), respectively, and lastly Proteus SPP recorded 4% (5) isolates. The number of colonies for each of Acetic acid and Dettol was calculated before and after sterilization. The highest value of colonies before sterilization (2.93 × 10² bacteria / 100 ml) and the lowest value was 0.0 after sterilization (acetic acid samples) and the highest value for Dettol samples ( 2.17 x 10² bacteria / 100 ml). The study showed the superiority of acetic acid with high efficiency in the sterilization process compared with Dettol solution, the acetic acid at a concentration (4-6%) gave a high efficiency in the process of sterilization and disinfection of classrooms by (100%) ) compared with Dettol solution.
