Figure 4

E. coli growth inhibition by Lev–MCD (1:2), CLev = 0.10 (a); 0.05 (b) and 0.03 μg/mL (c) with adjuvant EG–MCD (1:2, the concentrations of EG are indicated in the figure). B. subtilis growth inhibition by Lev–MCD (1:2), CLev = 0.5 (d) and 1.0 (e) μg/mL with adjuvant menthol–MCD (1:2, the concentrations of menthol are indicated in the figure). The molar ratio of the components is given in parentheses. Small bold red crosses refer to the absence of bacterial growth inhibition. Red crosses indicate the diameter of growth inhibition zone. pH 7.4 (0.01 M PBS), 37 °C, 24 h of incubation. MCD: methyl-β-cyclodextrin.
