The purpose of my experiment was to test the effect of a ginkgo biloba leaf extract on the inhibition of bacteria's bacillus subtilis and bacillus megaterium growth. Previous studies have stated that ginkgo biloba may have antibacterial properties. In my experiment, I incubated the bacteria and then added circular filter papers dipped in ginkgo biloba to each Petri dish and incubated again. I then checked for rings of inhibition that would have occurred if the ginkgo biloba had antibacterial properties. My results were inconclusive, and showed that little or no inhibition of the bacteria had occurred.
