Investigating the Antimicrobial Activity of Vancomycin-Loaded Soy Protein Nanoparticles

Figure 5

Antimicrobial activity of vancomycin and vancomycin/soy protein nanoparticles (vancomycin-SPNs) based on RDA test on Staphylococcus aureus (a) and Streptococcus pyogenes (b). Minimum inhibitory concentration (MIC) values for vancomycin and vancomycin-SPNs (c). (1) 15:05 (mg/ml of vancomycin:SPNs); (2) 10:15 (mg/ml of vancomycin:SPNs); (3) 6:20 (mg/ml of vancomycin:SPNs); (4) 8:25 (mg/ml of vancomycin:SPNs); (5) 10:30 (mg/ml of vancomycin:SPNs), and (6) vancomycin.
