Effects of 80 AU ml⁻¹ of purified antimicrobial peptide AN5-1 produced by P. alvei AN5 on early exponential growth phase against target strains: a E. coli ATCC 29522, b S. marcescens, c S. aureus and d B. cereus ATCC 14579, in the absence (filled circle) and presence (filled triangle) of antimicrobial peptide AN5-1. The bacterial growth was measured by means of optical density at 600 nm (OD₆₀₀)
