P. aeruginosa killing curves. Exponential phase cultures of P. aeruginosa PA7 were challenged for 24 h with tobramycin at concentrations corresponding to 1/2× the MIC, the MIC, and 2× the MIC, alone or combined with 40 µg/mL o-CH3 (A) or 320 µg/mL p-CH3 (B) berberine derivatives (BDs). A culture exposed neither to antibiotics nor to compounds was used as a growth control (C). The reported results are the average of two replicates ± standard deviation.
