Abstract

The present research, the antimicrobial activity of nanoparticles against the most important food deleterious bacterial and fungal species was evaluated. Three types of oxides (Ag, Ti and Zn) nanoparticles at different concentrations 25-200 mg/mL were used for antifungal, antibacterial and anti-yeast activities evaluation alone and in combination. The experimental results showed the effectiveness of Ag nanoparticles to inhibit the activity of a number of selected bacteria such as Klebsiella pneumoniae, which showed the most activity with the inhibition area of 11 mm and 7 mm in case of Escherichia coli. The nanoparticles also showed promising antifungal and anti-yeast activities, especially when the nanoparticles were used in combination. The findings revealed that the oxides of silver, zinc and titanium nanoparticles have promising antifungal, antibacterial and anti-yeast activities, which could find potential applications in biomedical field.
