This is a lab report studying the effects of common foods on bacteria. Works cited included.

Introduction         Bacteriology is the study of bacteria, especially as it pertains to medicine (Carter 323). Bacteriology is oddly arouse in the effects of certain products, potential antibiotic drugs, on bacteria. The propose of this look into was to test the effects of common foods, spurt tea, honey, and garlic, on bacteria, thus discovering if any of the fore stated products countenance antibiotic qualities. An antibiotic is any product that can extirpate or inhibit the development of other microorganisms (342). Antibiotics are utilize in a variety of products including soaps and lotions, as well as in medication to prevent the growth of such microorganisms. It is relatively cushy to quantify the effects of antibiotics on bacteria by victimization the disk diffusion test (345). The potential antibiotic is impregnated onto dribble disk in the center of a ontogeny farming of bacteria. Thus the antibiotic is allowed to diffuse onto the adjacent interme diate providing a gradient of the antibiotic. After the culture is properly incubated, a bacterial lawn go out appear in the plate. If the antibiotic agent is effective, then a regularize of inhibition of bacterial growth will form around the disk (343). The zone will pick up like a sportsmanlike space in bacterial growth.

The size of the zone is certified of three things: the diffusion gait of the antibiotic, the degree of sensitivity of the bacterium, and the growth rate of the microorganism (Garrity 97). The experiment tested the effects of three potential antibiotics on both types of bacteria, E. Coli and Bacillus. These were selected based on the ! fact that these two types of bacteria calumniate into the two different categories. E. Coli is Gram-negative appearing pink after(prenominal) stained, and Bacillus is gram-positive, appearing violet. Gram spying is used to categorize bacteria based on the behavior or absence of a peptidoglyc layer (Purves... If you want to bum around a plenteous essay, order it on our website: BestEssayCheap.com
