FIGURE 3.

Effect of E. indicum SJ16 extract on biofilm formation and planktonic growth of P. aeruginosa. Different concentration of bacterial extracts (0.2–1.2 mg/ml) ware tested against the biofilm forming reference P. aeruginosa strains PAO1 (A) and PAH (B). The same concentrations of bacterial extracts were also tested for the inhibitory effect on the planktonic growth of PAO1 (C) and PAH (D) strains. Tests without extract and with methanol were considered as control and negative control, respectively. “^∗”, “^∗∗” and “^∗∗∗” Indicates significant differences from the control at P < 0.05, P < 0.01, and P < 0.001, respectively.
