Generation and Characterization of Silver Nanoparticles in Mentha pulegium Extract and Evaluation of Biological Activities of the Prepared Extract

Table 1

Antibacterial activity of biosynthesized silver nanoparticle extract from M. pulegium, against bacteria. The results were expressed as IZ: inhibition zone diameters (mm); MIC: minimum inhibitory concentration; MBC: minimum bactericidal concentration, evaluated by disc diffusion and determination of MIC and MBC tests.
