FIG 1.

(A to D) Antibacterial effect of GML (A, B) and lauric acid (C, D) on the viability of S. aureus biofilms cultivated with or without 20 μg/ml (A, C) or 1 μg/ml GEN (B, D). Compared to 0 mM GML or lauric acid, both GML and lauric acid decreased (#, P < 0.01) bacterial viability in the absence of GEN. In the presence of GEN, GML and lauric acid each acted synergistically to decrease (*, P ≤ 0.01) bacterial viability compared to the corresponding concentration of GML or lauric acid alone. Each data point represents four biofilms. The lower detection limit was 1.7 log₁₀ CFU per biofilm. Avg, average; SE, standard error.
