Depolarization of the cytoplasmic membrane of cells of S. enterica ser. Typhimurium treated with Lippia graveolens essential oil at MIC (
), with 30 mM PMB (
) and 4 mM CTAB (
) monitored by fluorescence intensity change. Untreated cells were used as negative controls (
). Mean values of triplicate independent experiments and standard deviations are shown. * Significant differences between treatments compared to the control (p < 0.05).
