In this Science Buddies science project, you will measure the effectiveness of different antimicrobial agents by measuring zones of inhibition on bacterial culture plates. You can customize this kit to include the nutrient agar plates, living K-12 E. coli, dissecting forceps, and other supplies needed to complete this experiment.

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.
