Özet:    In this study, the effect of NaCl and pH on the inhibitory spectrum and activity of enterocin KP produced by Enterococcus faecalis KP was determined. Lactobacillus plantarum, Listeria monocytogenes, Escherichia coli O157:H7 and Salmonella Typhimurium were used as target microorganisms. At the end of the study, the inhibitory activity of enterocin KP was increased in the presence of NaCl at concentrations of 4-7%. Also, low pH (5.0-5.3) condition either caused an increase enterocin KP activity or rendered Escherichia coli O157:H7 sensitive to enterocin KP. However, acidic and neutral pH did not affect its activity. In conclusion, a synergist effect was occurred and inhibitory activity of enterocin KP increased when it was used in combination with NaCl or under acidic condition.
