FIG. 6.
E. coli Ti05, P. aeruginosa, and methicillin-resistant S. aureus were incubated for 4 h in the dark with 5-ALA and MAL. Bars represent the total bacterial PAPs produced. Dotted lines (○) represent the survival fraction after incubation (dark toxicity), while solid lines (▪) represent the survival fraction after PDT (120 J·cm−2). Note the different scales used for Pseudomonas.
