Disinfectant Lab Report
Introduction
The purpose of this experiment is to discover which type of bacterial inhibitor, antiseptics (Hydrogen Peroxide), disinfectants (Ammonia), or antibiotics (Erythromycin) are the most effective; in other words, which type of bacterial inhibitor will create the largest zone of inhibition in millimeters squared. In doing this experiment, the researchers will reveal which bacterial inhibitors abolish the most bacteria. In the future, people will choose the most effective bacterial inhibitor; therefore, they save both money and time. If the disinfectants are applied to the bacteria, then the zone of inhibition will increase because disinfectants are antimicrobial agents that are applied to non-living objects, and a petri dish is a nonliving …show more content…
Bleach was the most effective disinfectant because it destroyed 241.678 mm2 of bacteria, whereas the Ammonia had no effect on the bacterial growth. Finally, with the antiseptics, Iodine created the largest zone of inhibition (273.9775 mm2); thus making it the most effective out of the three antiseptics. When discussing the overall average of each bacterial inhibitor’s zone of inhibition, the antibiotics were the most effective because it destroyed 271.2171 mm2 of bacteria; thus, creating the largest zone of inhibition out of the three bacterial inhibitors. The disinfectants, on the other hand, created the smallest zone of inhibition (98.1341 mm2); moreover, the disinfectants were less effective compared to antibiotics and antiseptics. As a result, this experiment rejected my hypothesis that if the disinfectants are applied to the bacteria, then the zone of inhibition will increase because disinfectants are antimicrobial agents that are applied to non-living objects, and the petri dish is a nonliving object. There are many different types of antibiotics; however, they all have one thing in common: the ability to inhibit and abolish the growth of microorganisms by destroying their cell wall. According to Microbiology Online, antibiotics are the most effective bacterial inhibitor because they take advantage of the difference between bacterial cell’s structure and the host’s cell’s structure. Nevertheless, ever since the Alexander Fleming’s discovery of Penicillin in 1928, bacteria has evolved antibiotic resistance by changing in some way that reduces the effectiveness of the
