Effect of protease inhibitors on antimicrobial activities of MP-V1 in the increased Salmonella population density. The effect of a protease inhibitor cocktail (Sigma-Aldrich, Milwaukee, WI, USA) and its components (23 mM 4-(2-aminoethyl)benzenesulfonyl fluoride (AEBSF), 2 mM bestatin, 0.3 mM pepstatin A, 0.3 mM E-64 and 100 mM EDTA) on antimicrobial activities was examined using 0.5 to 10 μL doses against 108 cfu/mL of Salmonella Enteritidis (A); Salmonella Gallinarum (B); and Salmonella Typhimurium (C). The MP-V1 was used at the MICs determined in 106 cfu/mL. Data are means ± SE (n = 3). Different letters indicate significant differences by the one-way ANOVA/Duncan (p < 0.05).
