    Antibacterial activity of lactobacillus species against pathogens of seafood origin
    (Society of Fisheries Technologists(India),Cochin, 2003) Nair, P.S.; Surendran, P.K.
    Lactic acid bacteria(LAB) were isolated from seafoods. Among the LAB, Lactobacillus was the predominant genus isolated. The Lactobacillus species identified were Lactobacillus plantarum, L. gasseri, L. buchneri, L. alimentarius, L. fermentum, L. acidophilus, L. animalis and L. reuteri. L. plantarum was the predominant Lactobacillus species in the seafoods tested. The biochemical and antibacterial activity of selected cultures were studied. The antibacterial activity of Lactobacillus cultures were tested against pathogenic bacteria like Listeria monocytogenes, Salmonella typhimurium, Bacillus cereus. Escherichia coli, Staphylococcus aureus, Vibrio choleroe and V. vulnificus. The Lactobacillus cultures showed highest antibacterial activity against L. monocytogenes and B. cereus. The bacteriocins from LAB cultures were active against other LAB cultures. The cherecterization of the antibacterial factor confirmed the presence of bacteriocins in Lactobacillus cultures from seafood.
