Figure 6. Photoinactivation of P.aeruginosa by THPTS.

Figure 6

Photoinactivation of P.aeruginosa (DSM1117) by THPTS photosensitizer (PS) after incubation times of 30, 90 and 180min in PBS (A) and PBS+10% HS (B). 100µM of THPTS for 30min or 10µM of THPTS for 90min were sufficient to obtain a total bactericidal effect leading to the complete absence of colony. Serum addition completely abolished the bactericidal effect of THPTS for this bacterial strain. Viability of bacterial cells was determined by a CFU assay. Each bar is the mean ± standard deviation of three experiments (P<0.005). CD: control in the dark, CL: control with light, PI: photoinactivation.
