Abstract
In this study, the extract of Lavandula stoechas for production of silver and zinc oxide nanoparticle without use of any chemical agent was investigated. The silver (AgNPs) and zinc oxide nanoparticles (ZnONPs) showed strong antibacterial activity against both tested Escherichia coli 0157:H7 (Gram negative) and Staphylococcus aureus (Gram positive) bacteria. The antibacterial activity of bio-synthesized nanoparticles against two pathogens was assessed by minimal inhibitory concentration (MIC) assays. The MIC values ofAgNPs and ZnONPs of 10.63 mu g/mL and 12.5 mu g/mL for E.coli 0157:H7 AgNPs and Staphylococcus aureus against ZnONPs were at 3.32 mu g/mL and 6.25 mu g/mL respectively.
