Antibacterial Observation

Results: In the experiment we saw six locations show bacterial samples. These locations were the soap dispenser in the men’s bathroom, the inside front door handle to building H, the first floor elevator button, the first floor water fountain button, and both the men’s and women’s bathroom trash can rim. Between the six locations, there was a species richness of at least one in all but four locations. Furthermore, the color and size of each colony differed from location to location. At the first floor water fountain button, of the four small-sized colonies, two were white and two were yellow. The most diverse samples came from the men’s and women’s bathroom trash can rim with a total of six species richness. A major trend in the observed data was both the men’s and women’s bathroom trash can rims contained far

Another possible trend may be where janitors clean will likely contain less bacterial samples, such as the water fountain buttons, elevator buttons, and front entrance door handles.

Discussion:

The hypothesis that “bacteria cultures in the men’s bathroom, the third floor elevator and water fountain buttons, and the outside front door handle will have a higher bacterial species abundance and richness than in the women’s bathroom, the first floor elevator and water fountain buttons, and the inside front door handle” was rejected all but one time. The exception to my hypothesis being rejected was the men’s bathroom soap dispenser which held a species richness of one, while the women’s bathroom soap dispenser contained no bacterial samples. Another reason my hypothesis was rejected was due to both the outside front door handle, the
