| description | In this work, we aimed to study the chemical composition of the essential oils from bulbs and leaves of two cultivars of <i>Allium sativum</i> L. and two of <i>A. ampeloprasum</i> L. var. <i>holmense</i>. Moreover, we investigated their activity against four common bacterial strains responsible for food contamination (<i>Listeria monocytogenes</i>, <i>Escherichia coli</i>, <i>Acinetobacter baumannii</i>, and <i>Staphylococcus aureus</i>) by formation of biofilms. The susceptibility of bacterial biofilms was evaluated by crystal violet assay, whereas the metabolic changes occurring in the bacterial cells were ascertained through the MTT test. The essential oils were characterized by the presence of most characteristic components, although with different composition between the species and the cultivars. The essential oils inhibited the capacity of the pathogenic bacteria to form biofilms (up to 79.85 against <i>L. monocytogenes</i>) and/or acted on their cell metabolism (with inhibition of 68.57% and 68.89% against <i>L. monocytogenes</i> and <i>S.</i> <i>aureus</i>, respectively). The capacity of the essential oils to act against these foodborne bacteria could suggests further ideas for industrial applications and confirms the versatility of these essential oils as food preservatives. |
