چکیده مقاله
One of the most important factors in food industry is the formation of microbial biofilm which can be the potential source of food products contamination with food spoilage and foodborne pathogenic bacteria Nanotechnology is considered as a promising solution to produce and develop such novel antimicrobial substances The potential effects of nanostructured metal oxides on the reduction of such contaminants are well established The goal of this study was to see how well magnesium oxide MgO and copper oxide CuO nanoparticles NPs inhibited growth and biofilm formation of two common foodborne bacterial pathogens This study was completed in the year 2020 Resazurin reduction and micro dilution procedures were used to assess the minimum inhibitory concentration MIC of magnesium oxide and copper oxide nanoparticles for Escherichia coli O157: H7 ATCC 35218 , Listeria monocytogenes ATCC 19118 , Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 14028 Magnesium oxide nanoparticles had MICs of 2, 2, 2 and 4 mg/ml, while copper oxide nanoparticles had MICs of 1, 0 16, 0 5 and 0 25 mg/ml against E coli, L monocytogenes, Staph aureus and P aeruginosa respectively At the MIC, the magnesium oxide nanoparticles inhibited biofilm formation of E coli, L monocytogenes, Staph aureus and P aeruginosa by 89 9, 96 6, 98 3 and 98 3 percent and the copper oxide nanoparticles inhibited biofilm formation 88,97 7, 93 6 and 98 7 percent, respectively Both compounds had inhibitory effects on E coli, L monocytogenes, Staph aureus and P aeruginosa according to our findings Even at sub MICs, NPs were found to be able to prevent biofilm development MgO and CuO nanoparticles can be utilized as a cleaning agent for surfaces to avoid the formation of foodborne bacterial biofilms, which is important for public health
