Phenazine production by 508ΔPACI in LB medium containing AHLs at concentrations of 0.1 (black bars), 1 (gray bars), and 10 μM (white bars). Relative phenazine production was evaluated using the value of A₃₆₅/OD₆₀₀; the maximum value obtained for 10 μM 3-OH-C6-HSL was set as 100%. Results were reproduced in three repeated experiments, and error bars indicate standard deviations.
