Hemmat, M., Ibrahim1; Reham, A., Amin1; Nesreen, Z., Eleiwa2 and Heba, G., Rezk3


Zinc oxide can be called a multifunctional material thanks to its unique physical and chemical properties. Practical application of zinc oxide nanoparticles (ZnO NPs) suspension with different concentrations (5, 8, and 10 mM) were investigated against Staphylococcus aureus artificially inoculated into broiler breast fillets. The results indicated that ZnO suspensions (5, 8 and 10 mM) had a significant inhibitory effect on the growth of Staphylococcus aureus during 12 days of refrigerator storage at 4ºC. Accurately, ZnO NPs 10 mM showed the highest reduction percentage (25.35%) to Staphylococcus aureus from 8.6 to 6.42 log cfu/g, compared to other concentrations (5 and 8 mM). Thus, that the antibacterial activity of ZnO was concentration dependent.
