Effect of protease inhibitor on the antimicrobial activity of the cell-free supernatant from L. taiwanensis. EDTA, a protease inhibitor, was added to the cell-free supernatant (77.1 μg peptides/mL, MIC50 against S. Gallinarum) from L. taiwanensis and this sample was used to examine the antimicrobial activity against S. Gallinarum. The y-axis and different letters (A, B, C and D) in the graphs represent the relative growth of S. Gallinarum and significant differences (p < 0.05), respectively.
