Identification of antifungal peptides produced by Lactobacillus plantarum IS10 grown in the MRS broth

The use of secondary metabolites of lactic acid bacteria for preservation of foods is increasingly gaining interest to the food industry to replace synthetic preservatives. In this study, the cell free supernatant containing peptides obtained from Lactobacillus plantarum IS10 was fractionated by siz...
