aThe final concentrations of NaCl, KCl, NH4Cl, MgCl2, ZnCl2, CaCl2, and FeCl3 were 150 mM, 4.5 mM, 6 μM, 2 mM, 8 μM, 1 mM, and 4 μM, respectively, and the control MIC values were determined in the absence of these physiological salts. The data were derived from a representative value of three independent experimental trials.
