Bactericidal Activity of TiO₂ on Cells of Pseudomonas aeruginosa ATCC 27853

Figure 4

Effect of light and TiO₂ concentration on viability of the Pseudomonas aeruginosa ATCC 27853 exposed to (a) 0.5 mg mL⁻¹ TD and P25 and (b) 1 mg mL⁻¹ TD and P25. In both plots, the control data (light exposure without TD and P25) are displayed as black squares.
