for charged and polar molecules, while
apolar compounds (e.g., monoterpenes and sesquiterpenes) can
readily penetrate the lipidic bilayer, whose hydrophobic interior is
a perfect matrix for lipophilic molecules. Interaction between the
EO components and bacterial membranes produces major structural
changes, and the accumulation of these compounds in the
hydrophobic part of the membranes modifies their permeability,
sometimes causing swelling (Sikkema et al. 1995; Carson et al.
2002; Burt 2004). According to Juven et al. (1994) and Sikkema et al.
(1995), this interaction has two possible mechanisms of action:
by accumulation in the lipidic bilayer, distorting the lipid–protein
interaction; or binding the hydrophobic parts of the membrane
proteins. All the above will eventually result in cell death.
