ISOLATION, PURIFICATION AND CHARACTERIZATION OF ANTIBACTERIAL PEPTIDE FROM SOIL IN PANVEL REGION

Microbes contend for the limited space and nutrients present in natural ecological niches, thus they've
developed several strategies in order to survive. Production of ‘antimicrobial peptide’ best known as
‘Bacteriocin’ is one of them. Bacteriocins extensively distributed in nature which are synthesized by bacteria.
The present study was carried out to estimate naturally synthesized antimicrobial peptides and their
capacities to inhibit Gram-positive pathogenic organisms. Ten bacterial spp. were isolated and screened to
produce antimicrobial peptide. Antimicrobial peptide produced by two of bacterial strains showed the most
significant antimicrobial activity against Staphylococcus aureus. Bacteriocins have shown significant
activity at 370 with pH 7 Proteolytic enzymes verified the proteinaceous nature of antimicrobial peptides.
These partially purified bacteriocins can be further used as antimicrobial agent or it can be used as food
complements to control food borne pathogens.
