The MIC values (µM) of the peptides against E. coil ATCC 25922 in the presence of physiological salts

Peptide	Controla	MIC under physiological salt concentrationb
		NaCl	KCl	NH4Cl	MgCl2	CaCl2	ZnCl2	FeCl3	GM	Fold
FR	8	> 32	8	8	32	> 32	8	16	19.50	2.44
rLG	2	2	2	2	4	> 32	2	2	3.62	1.81

^aThe control MIC values were determined in the absence of physiological salts and serum

^bThe final concentrations of NaCl, KCl, NH₄Cl, MgCl₂, CaCl₂, ZnCl₂, and FeCl₃ were 150 mM, 4.5 mM, 6 µM, 1 mM, 2 mM, 8 µM, and 4 µM, respectively
