Abstract

The purpose of this experiment was to determine the effect of sports drinks on microbes that are active in the stomach. The researchers hypothesized if microbes found in the gut are exposed to sports drinks, then the different drinks will affect the growth of Lactobacillus acidophilus and Escherichia coli. The experimenters prepared 60 petri plates with mixed agar and 1 milliliter of the sports drink (5 for each drink). They plates were put into lab fridge to wait until jelly like substance (1 day). The first sports drink was tested with 10 petri dishes (5 of the Lactobacillus acidophilus and 5 of the Escherichia coli). When all 60 petri plates were filled with elements, the researchers waited 48 hours. When the data was analyzed, the researchers didn't see a change in the petri dishes so no data was collected. The results were recorded in google sheets. In conclusion, the researcher's hypothesis was refuted. The data shows that there was no effect of sports drinks on bacteria.
