Figure 6

Effect of AiiK on biofilm formation in P. aeruginosa PAO1. (a) Biofilm formation by P. Aeruginosa PAO1 represented by crystal violet staining and planktonic cells of P. Aeruginosa PAO1. (b) The crystal violet staining of biofilm formed by P. aeruginosa PAO1. Lanes 1–3: 0 μg/mL of AiiK; Lanes 4–6: 5 μg/mL of AiiK; Lanes 7–9: 10 μg/mL of AiiK. (c) Fluorescence microscopy for visualization of biofilm formation by P. aeruginosa PAO1 stained with acridine orange.
