Title

Anti-Listerial Activity of Four Seaweed Essential Oils Against Listeria monocytogenes

  0-0

Abstract

 Background: Listeria monocytogenes is one of the most virulent types of bacteria and causes severe foodborne illness, such as listeriosis. Because this pathogen has become resistant to sanitizers and other disinfectants that are used to clean utensils and surfaces during food processing, it poses a serious threat to the food industry. Objectives: The study was conducted to determine the anti-listerial potential of Essential Oils extracted from four edible seaweeds against L. monocytogenes. Materials and Methods: Essential Oil was extracted from four edible seaweeds (Enteromorpha linza, Undaria pinnatifida, Laminaria japonica, and Porphyra tenera) against L. monocytogenes using the microwave hydrodistillation method. The anti-listerial activity of the Essential Oil was determined using the standard disc diffusion method. Results: Among the four Essential Oils, E. linza (ELEO) was most effective against all three strains of L. monocytogenes (11. 3-16. 0 mm). The other three Essential Oils were only effective against two strains, L. monocytogenesATCC 19115 (10. 0-10. 5mm)and L. monocytogenes ATCC7644 (11. 0-15. 0mm). Theminimuminhibitory concentrationandtheminimumbactericidal concentration of all four Essential Oils varied from 12. 5-25. 0 mg/mL. Further, the mode of action of ELEO against L. monocytogenes was investigated by examining its effect on cell viability, the release of 260-nm absorbing materials, the number of K+ ions, the relative electrical conductivity, and the salt tolerance capacity. The results indicated that the Essential Oils exhibited strong anti-listerial activity against multiple strains of L. monocytogenes. It displayed potential inhibitory effects on the viability of bacterial cells and loss of integrity as indicated by an increase in the relative electrical conductivity, leakage of K+ ions and other 260-nm absorbing materials, and a loss of the salt tolerance capacity. Conclusions: The results presented herein provided insight into a possible explanation for the modes of action of Essential Oils on L. monocytogenes. The outcome of the present study may aid the food industry in locating the most promising potential antilisterial agents from edible seaweed sources to control L. monocytogenes and also in facilitating their application in food processing and preservation techniques in a nontoxic and environmental friendly manner.
