The rescue of the swarming of ΔepsT with surfactin. (A) Wild SM9913 on a swarming plate without surfactin. (B) ΔepsT on a swarming plate without surfactin. (C) Wild SM9913 on a swarming plate with surfactin. (D) ΔepsT on a swarming plate with surfactin. Five microliters of surfactin (2 mg/ml) were dropped onto the center of the plate before inoculation. (E) Colony diameters of wild SM9913 in (A) and (C) and ΔepsT in (B) and (D). Data were from three independent experiments with at least three replicates (mean ± SD). P-value was calculated from t-test and the symbol ∗ indicates that the difference in colony diameter between ΔepsT with or without surfactin was significant (P < 0.001). Pictures are a representative of three independent experiments.
