This experiment determined whether garlic was effective in fighting bacteria. This project interested me because garlic is traditionally used in medicine and is known to combat bacteria.
If bacteria is exposed to garlic, then the garlic will to abolish the Escherichia coli, because the Escherichia coli (E. coli) is usually a weak bacteria.
Have three petri dishes prepared with blood agar, and three test tubes with 100 milliliters of milk. Label three test tubes, “A,” “B,” and “C.” With a toothpick, add a small amount of the E. coli specimen to tube “B"; shake the test tube to mix throughly. For test tube “C,” add the same amount of E. coli and five millimeters garlic juice. Shake the test tube. Allow all test tubes to incubate for two hours. Mark the petri dishes “A,” “B,” and “C.” Use a syringe to extract 10 milliliters of the mixture from test tube “A” and place it in the center of petri dish “A.” Using a new syringe, repeat the previous step with mixtures “B” and “C.” Replace the lids and store the petri dishes in a cool, dry and shaded place. Record the diameter of the E. coli everyday for five days.
Petri dish “C,” with garlic juice show no signs of bacterial growth. The other dishes showed growth.
I accept my hypothesis. The petri dish containing garlic juice did not show any signs of bacterial growth. My findings suggest that garlic is very effective in preventing bacterial growth. This information is useful for people who are trying to prevent prostate cancer and the common cold.
