(A) Biofilm inhibition effect of grapefruit seed extract (GSE) at 1/2 × minimum inhibitory concentration (MIC) and CFS; (B) biofilm degradation effect of GSE at 1/2 × MIC and CFS. The MIC of GSE against S. aureus ATCC 6538, S. aureus ATCC 12692, and S. aureus ATCC 25923 was 50, 25, and 100 μg/ml, respectively. All experiments were performed in triplicates, and reported values represent the mean ± standard error. a-cDifferent letters in the same bar indicate significant differences (p < 0.05).
