Abstract:
In this study, the antibacterial properties of the volatile components of four essential oils (cinnamon, clove, origanum, and peppermint oil) and five of their components (allyl isothiocyanate (AITC), carvacrol, citral, eugenol, and (+)-limonene) against five food-related bacteria (Escherichia coli, Listeria monocytogenes, Salmonella Typhimurium, Pseudomonas fluorescens, and Enterococcus faecalis) were evaluated. The results of disc volatilization method revealed that AITC exhibited antibacterial activity against the five tested strains at the lowest concentration, as did cinnamon oil and carvacrol. Moreover, the total aerobic bacterial count in coleslaw salad was suppressed in all test groups treated with AITC compared to that in control.

Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
