Antagonistic Activity and Surface Decontaminant Potential of Lactic Acid Bacteria from Fermented Oreochromis niloticus

Lactic acid bacteria (LAB) have been extensively explored as potential biopreservants. They could produce substances with antimicrobial properties such bacteriocins and organic acids which can also be the cause of antagonistic activity shown by LAB. Thus, objective this study is to assess LAB isolated from fermented Oreochromis niloticus against foodborne pathogens determine a surface decontaminant raw chicken breast Tilapia fish fillet. The has affect Escherichia coli, Salmonella typhimurium, Staphylococcus aureus. When was introduced mixed cultures E. S. aureus, growth those drastically reduced proven that grows stronger more stable while eliminating pathogens. their cell-free supernatant (CFS) were into fresh fillet, where coli recorded. Both cell CFS showed inhibition on fillet in range 0.16 1.28 log10 reduction 0.12 1.12 reduction, respectively. In conclusion, results above suggest O. decontaminant. Additionally, both used biopreservative for due very good toward
