Abstract

Bacteriocins are a kind of antimicrobial peptides that kill or inhibit the growth of bacterial strains. The purpose of this study was to investigate the antibacterial effect of on several pathogenic bacterial strains. Bacteriocin produced by was purified by chromatography with Sephadex G-75 column, and its antibacterial effect on gram-negative bacteria, including ATCC 700928, PTCC 1707, PTCC 1621, PTCC 1693, and PTCC 1755, were evaluated by the disk diffusion method. The structure of bacteriocin was determined by nuclear magnetic resonance spectroscopy. The interaction of bacteriocin with the antigen 43 (Ag43) of was evaluated by the molecular docking method. Bacteriocin extracted from bacterial isolates had antibacterial activity on strains but not on other studied strains. Bioinformatics analysis also showed bacteriocin docking with Ag43 with an energy of -159.968 kJ/mol. Natural compounds, such as bacteriocin, can be an alternative to common chemical compounds and antibiotics. To reach a definite conclusion in this regard, there is a need for further research and understanding of their mechanism of action.
