| Abstract | This experiment sought to investigate the efficacy of antibacterial chemicals (e.g. 70% isopropyl alcohol, 99% isopropyl alcohol, Bleach, Virex cleaner, glass cleaners) compared to “natural” antibacterial agents (e.g. tea tree oil, lemon juice). This was accomplished by exposing bacteria grown on agar to the agents and then measuring the resulting “zones of inhibition”. |
