FIG 1.

Planktonic growth curves and MBCs for P. aeruginosa ATCC 39324 in ASM⁺, ASM⁻, and LB medium. (a) Numbers of CFU per milliliter in planktonic cultures as a function of time in different growth media. Growth curves were performed in duplicate, with error bars denoting the difference between the two experiments. (b) MBCs for planktonic P. aeruginosa upon 24-h exposure to the different antimicrobials in PBS. MBC values were determined in triplicate with separately grown bacterial cultures, which yielded no differences in MBC values.
