Figure 7

Synergistic combination effect of macrolactin A and C14 surfactin against S. aureus ATCC 33592 (methicillin-resistant MRSA strain). Dose–response of macrolactin A without surfactin (black cross) is compared with increasing sub-MIC concentrations of surfactin C14 (0.5–2 µg/mL surfactin, light grey to black dots). Data is depicted as average values ± standard deviations from four independent experiments, n = 4.
