Investigating the antibacterial activity of copper oxide nanoparticles against Vibrio parahaemolyticus and Escherichia coli

This study has investigated the antimicrobial effects of copper oxide nanoparticles (CuO NPs) against the foodborne pathogens Vibrio parahaemolyticus and Escherichia coli. CuO NPs were biosynthesized using Bacillus sp. HM۱ characterized by Ultraviolet-Visible (UV-vis) and Fourier-transform infrared (FTIR) spectroscopy, and evaluated for their minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Results showed remarkable antimicrobial activity, with MIC values of ۲ mg/ml for E. coli and ۶۲.۵ µg/ml for V. parahaemolyticus, indicating the potential of CuO NPs as effective agents for controlling these bacterial infections in aquaculture and food safety applications.
