Figure 5

Comparative graphs to show the differences in inhibition of viable colony forming units of Gram-positive S. aureus and Gram-negative P. aeruginosa on the unit surface area (CFU/cm2) of SNAP films, BPAM films and SNAP-BPAM films as compared to control CarboSil. The results suggest that both SNAP and BPAM has different degree of toxicity towards gram positive and negative bacteria. While BPAM by itself has better antibacterial potential towards gram negative P. aeruginosa as compared to SNAP, SNAP is better than BPAM w.r.t its bactericidal action against gram positive S. aureus. The combined action of SNAP-BPAM works equally well against both the bacteria. The data is reported as a mean ± standard deviation for n=3 samples and the significance with a p-value < 0.05 is stated for comparisons.
