Isolation, Optimization, Production and Purification of Bacteriocin

Lactic acid bacteria (LAB) occur naturally in several raw materials like milk, meat and flour used to produce foods. Bacteriocin is proteinaceous antibacterial compounds, which constitute a heterologous subgroup of ribosomal synthesized antimicrobial peptides. Bacteriocin can be used as bio preservatives in fermented foods. The strains of lactic acid bacteria have also potential to act as a biopreservative or natural food preservative.
