Abstract
(type = abstract)
Listeria monocytogenes has gained increasing attention as a pathogen of public health importance owing to large numbers of foodborne outbreaks of listeriosis, led to this study. A wide range of essential oils (EOs) and natural products have been used to control Listeria monocytogenes. The reason for using essential oils is to preserve food by inhibiting the growth and proliferation of microorganisms in food due to its antimicrobial effects against microorganism, but their low water solubility limits their efficacy and application in food. This study included two objectives first, in the present study, 28 different essential oils were evaluated for their antimicrobial activities against Listeria monocytogenes.Various concentrations of EOs were introduced into brain heart infusion broth to determine the minimum inhibitory concentration (MIC) for the pathogen. The experimental data were fitted to the modified Gompertz model, and the lag phase duration and maximum growth rate were calculated and compared for each essential oil at various concentrations. Overall, our experimental results indicate that frankincense, eucalyptus, and fire needle oils had the strongest inhibitory effects against Listeria monocytogenes with MICs <2.4 µg/mL. Essential oils with moderate antimicrobial effects included key lime, cedar wood, egyptian geranium, nutmeg, peppermint, valerian, and ylang ylang. Second, the antibacterial effects of the essential oils derived from the extracts of cedar wood, copaiba, fire needle, frankincense, egyptian geranium, nutmeg, peppermint, valerian and ylang ylang against the Listeria monocytogenes, was investigated in the presence and absence of different, 17.59, 35.17 and 70.34 µg/ml, concentrations of the casein proteins. The lag phase durations and maximum growth rate of each essential oil were calculated and compared. The effectiveness of individual essential oil varied from one essential oil to the other. The influence of the food matrix such casein proteins, was tested and determined. The effectiveness of the essential oils in absence of casein proteins and in the presence 17.59 µg/ml of casein proteins was similar but further decreased in addition of 35.17 and 70.34 µg/ml of casein proteins.
