Therefore, our obtained results are in line with previous studies in
which EOs, ORs and PC have shown various degrees of antimicrobial activity
against foodborne pathogens. Themainmechanisms of action that
have been proposed for the antibacterial effects are the disruption of
bacterial membrane, creation of a permeability in the cell membrane,
cell constituent release, reduction of intracellular pH and the induction
of depletion of the intracellular ATP concentration by the hydrophobic
compounds that they are principally composed of EOs and ORs
(Oussalah, Caillet, & Lacroix, 2006; Burt, 2004). In this experiment, it
could be found that there was no antibacterial activity that was specific
against only one bacterial species. The only kind of specificity that could
be observedwas the absence of inhibition for Gramnegative in comparison
to Gram positive. These results would confirm the hypothesis of
membrane disruption since the membrane composition is the property
that differentiates the two groups (Gram positive and negative).
