Abstract
The effects of ascorbic acid (vitamin C) on the gram positive bacteria Staphylococcus aureus (S. aureus) and the gram negative bacteria Escherichia coli (E. coli) were studied using a serial dilution of concentrated vitamin C applied in a Kirby-Bauer disk diffusion assay. It was observed that higher concentrations of ascorbic acid are more effective in killing bacteria. It was also observed that the gram positive bacteria, S. aureus, is more susceptible than the gram negative bacteria, E. coli. Lastly, it was shown that a saturation of vitamin C at high concentrations was not achieved within the experimental parameters, as no plateau effect was observed. The possibility of ascorbic acid as an antimicrobial agent is worthy of future research due to its safety, versatility, and availability.
