Bleach Lab Report
Background:
Bacteria is a prokaryotic cell that reproduces using the process of binary fission. Binary fission is “The process in which a parent cell splits into two daughter cells of approximately equal size”(northwestern.edu). The reproduction of bacteria can be stopped using antimicrobials. Antimicrobials were created and are used “to destroy disease-causing microbes”(cdc.gov). That means that antimicrobials fight and destroy organism such as bacteria. We use antimicrobials to clean are house and protect ourselves from bacterias. One example of an antimicrobial that we use in our home is bleach. Bleach contains the ingredient hypochlorous acid. This ingredient “causes bacterial proteins to unfold and stick to one another, making them nonfunctional …show more content…
My hypothesis states if antimicrobial concentration increases, then the zone of inhibition will increase because the higher the concentration, the more the antimicrobial will disinfect the area of bacteria and thus the zone of inhibition will increase.The results of the lab do support my hypothesis.
Paragraph 2:
My antimicrobial was bleach. Bleach contains hypochlorous acid which “causes bacterial proteins to unfold and stick to one another, making them nonfunctional and leading to cell death”(publications.nigms.nih.gov). This shows in the 0% diluted solution which had an average zone of inhibition of 1.67 millimeters for the diameter. The solution was pure bleach and the hypochlorous acid was able to kill more bacteria than the 100%, 75%, and 50% dilutions. The 50 % diluted bleach, which had an average zone of inhibition of 1 millimeter fro diameter, was able to kill more bacteria than the 100% and 75% diluted solution, but was less successful compared to the 0% diluted solution, or pure bleach. Therefore the zone of inhibition does increase when the antimicrobial concentration increases.
