it is demonstrated as one of the most antibacterial EO components
(Hyldgaard et al., 2012). The lowest concentration of O. vulgare EO
(0.5% v/w) acted as bacteriostatic on DIL 1, DIL 2 and DIL 3 Listeria
populations; only after 11 days of preservation at 4 C, bacterial
concentration of DIL 4 (concentration higher than 40 CFU/g at T0)
reached 0 CFU/g (MBC). The 1% and 2% (v/w) concentration of O.
vulgare EO inhibited bacterial cells in time and bacterial concentration
dependent mode: Listeria concentration decreased continuously
reaching the lowest values at the end of the experiments (14
days of preservation at 4 C), and regression line slope coefficient
