The strain was found to produce an extracellular antimicrobial substance that was peptide in nature and effective Against Listeria monocytogenes, Lactobacillus plantarum, Staphylococcus aureus and Bacillus cereus. The antimicrobial peptide is assayed as non organic acid and non hydrogen peroxide. It is sensitive to proteolytic enzymes, resistant to heat, and active over a wide range of pH.
