Gathered from the data, it seems that commercial products are more effective than natural remedies; natural remedies made little if no contribution in inhibiting bacteria. This result however, does not signify that natural remedies are inadequate at inhibiting bacteria. It reflects that natural remedies are ineffective in inhibiting gram-positive bacteria.
First natural product:
Saliva for instance, is one of the body’s many defence mechanisms. Its main function is to prevent adhesion of bacteria to oral surfaces. This means that saliva does not specialise in killing bacteria. Research has indicated that saliva have anti-bacteria property derived from hydrogen peroxide (H2O2). Peroxide inhibit bacteria by destroying cell walls and damaging inner membranes, however its strength is not …show more content…
However, the results from this experiment indicated the contrary. This phenomenon is most likely not because the antibacterial properties in turmeric are ineffective against gram-positive bacteria, but rather as a result of not meeting the Minimal Inhibitory Concentration (MIC). Moreover, a variable may have altered the results. While all other products were tested in liquid form, turmeric was tested in powder form. Therefore, the results representing turmeric’s performance are unreliable.
First commercial product:
The graph indicates that hand sanitiser is the least effective product amongst all commercial products. Upon exposure to heat level of 30 degrees, ethanol alcohol in hand sanitisers would evaporate immediately, as instructed on the label. Once it does, it no longer has any antibacterial functions. The test subjects tested in this experiment were incubated at 37 degrees, therefore it can be postulated that during the experiment, alcohol evaporated followed by further bacteria proliferation, hence the low inhibition range.
