Objective: To determine the antimicrobial resistance of bacteriocin producing marine Lactic acid bacteria and to study the efficacy of bacteriocin against L. monocytogenes during fish preservation.
Methods: Lactic acid bacteria from scales and mucus of marine fish viz., Perca sp., Platax sp. and Tuna sp. which showed activity against different spoilage causing bacteria were subjected to antibiotic sensitivity testing. The LAB isolates were also screened for their antagonistic activity against L. monocytogenes and other pathogenic and spoilage causing bacteria by the well-diffusion method. The potent bacteriocin from L. lactis PSY2 was tested for its efficacy in combating L. monocytogenes challenged fresh fish fillets stored at different temperatures viz., 4, 0 and -18°C for 28 days and compared to that of the chemical preservat..
