Bacterial Growth

For the second bacteria growth plate that we did my partners and I took bacteria from the bottom of a shoe. We rubbed the bacteria all over the plate with a cotton swab and made four sections. The first section is controlled , so all we did was put a piece of paper towel in the first quadrant. For the second quadrant, we soaked a piece of paper towel in bleach. The third quadrant, we soaked the paper towel in hand sanitizer, and the for the fourth quadrant we soaked the paper towel in vinegar. The purpose of this was to see which liquid kills bacteria the most. The results that we got was that the bleach kills the bacteria the most because there was the least amount of  bacteria growth in that quadrant.
