Maximal growth rate (h-1), lag phase (h); a,b,cacross rows indicate significantly different (P ≤ 0.05) μm or λ values based on the presence (or lack thereof) of bacteriocin for each strain of L. monocytogenes grown in each different carbohydrates; x,y,zdown columns indicate significantly different (P ≤ 0.05) μm or λ values among strains grown in the same carbohydrate for each bacteriocin and the control.
