Abstract :

The present research has been made an attempt to investigate the bactericidal efficacy of gold nanoparticles (AuNPs) synergistically with the bacteriocin and commercially available peptide nisin on food blemishing microbes. The peptide of bacteriocin produced by Lactobacillus plantarum and Lactobacillus lactis incorporated with gold nanoparticles and alone. Similarly, nisin also incorporated with gold nanoparticles and alone. Then, both combined and individual effects were tested against food spoiling organisms and the results revealed the antibacterial activities were increased on combination of bacteriocin with gold nanoparticles as compared to nisin with nanoparticles. In addition to this Bacteriocin obtained from Lactobacillus plantarum showed most promising synergism as compared to Lactobacillus lactis peptide. Therefore, this study may be considered as a preliminary approach for combined effect of food preservative agent with nanoparticles against food spoiling organism, which may be used for the preparation of packaging materials to extend the shelf life of food in future.
