Abstract
In this work, the chemical composition of Thymus zygis subsp. gracilis collected from Ifrane, Morocco, along with the evaluation of the antibacterial, anti-biofilm of Listeria monocytogenes activities, larvicidal effect against L3 larvae of Anisakis, and antioxidant properties of its essential oil (TZG-EO), are reported. GC–MS and GC-FID analyses highlighted the presence of 84 volatile components and strong bactericidal and anti-biofilm activities against L. monocytogenes at a concentration of 0.02 % were demonstrated. Also, larvicidal effect against Anisakis larvae at concentrations of 0.01 and 0.005 % was attained leading to the death of all tested larvae within 4 h. The in situ antibacterial activity of TZG-EO (0.01 and 0.005 %) in smoked fish showed high efficiency against L. monocytogenes growth. TZG-EO could be used as potential antibacterial and larvicidal agents for fighting against foodborne pathogens and extending shelf life of food products.
