MIC values of peptides in the presence of physiological saltsa with E. coli ATCC25922 and P. aeruginosa ATCC27853.

aMinimum inhibitory concentrations (MICs) were determined as the lowest concentration of the peptides that anti-bacteria growth.bThe final concentrations of NaCl, KCl, NH4Cl, MgCl2, CaCl2, ZnCl2, and FeCl3 were 150 mM, 4.5 mM, 6 µM, 1 mM, 8 µM, and 4 µM, respectively, and the control MIC values were determined in the absence of these physiological salts.cThe medium contained all kinds of salts in physiological concentrations.
