Effect of Different Ratios of Mentha spicata Aqueous Solution Based on a Biosolvent on the Synthesis of AgNPs for Inhibiting Bacteria

Figure 5

Inhibition zone (mm) of AgNPs using Mentha spicata aqueous plant extracts at different concentrations by Agar well diffusion method against Escherichia coli ATCC 35218. The zone of inhibitions are, respectively, 12 ± 0.5, 13.5 ± 0.5, 14 ± 0.5, 15 ± 0.5, 14 ± 0.5, 13 ± 0.5. Key: 1 : 0.0625, 2 : 0.125, 3 : 0.250, 4 : 0.5, 5 : 0.75, 6 : 1 mM.
