Figure 2
(a) Growth curves of E. coli in LB medium inoculated with 107 CFU of bacteria in presence of different concentrations of Amp: (♦) 0 g/mL, (■) 50 g/mL, (▲) 75 g/mL, (×) 100 g/mL, and () 200 g/mL. (b) Growth curves of E. coli in LB medium inoculated with 107 CFU of bacteria in presence of different concentrations of Ag NPs synthesized using glucose: (■) 0 g/mL, (▲) 5 g/mL, (×) 10 g/mL, (♦) 15 g/mL, and () 20 g/mL. (c) Growth curves of E. coli in LB medium inoculated with three different populations of bacteria and two different concentrations of silver nanoparticles: (♦) 0 g/mL Ag NPs at 0.070 × 107/mL CFU, (■) 20 g/mL Ag NPs at 0.070 × 107/mL CFU, (▲) 0 g/mL at 0.130 × 107/mL CFU, (×) 20 g/mL at 0.130 × 107/mL CFU, () 0 g/mL at 0.262 × 107/mL CFU, and (●) 20 g/mL at 0.262 × 107/mL CFU. (d) Growth curves of E. coli in LB inoculated with 107 CFU of bacteria in the presence of silver nanoparticles of different size at concentration of 20 g/mL: (♦) no treatment, (■) treated with Ag NPs synthesized glucose as reductant, and (▲) treated with Ag NPs synthesized ribose as reductant.
