Figure 2. MB plus KI enhanced aPDT of E. faecalis.

Figure 2

(A) KI (100mM) reduced MB concentration needed for E. faecalis aPDT using 6 J/cm2. (B) KI concentration effect on potentiation of MB (0.1 or 0.4μM) aPDT using 6 J/cm2. (C) KI (100mM) reduces light dose needed for E. faecalis MB (0.1–0.4μM)-aPDT. (D) MB plus KI aPDT for E. faecalis sampled at different time after the end of illumination. (E) Hypoxic antimicrobial effect of MB (0.4μM) plus KI (100mM) aPDT for E. faecalis using 6J/cm2. (F) Photoactivation of MB with or without KI to kill E. faecalis biofilm at 30 J/cm2 of light, the biofilms were formed in 6 well plates. (*P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001).
