Abstract
Seven strains of lactic acid bacteria (LAB) were tested for the production of
bacteriocins or bacteriocin-like substances by the agar spot method. By excluding inhibition
due to acid and confirming their proteinaceous nature, the inhibitors were confirmed as
bacteriocins. The ability of four bacteriocin producing strains, viz., Lactobacillus plantarum
89, L. plantarum 8014, L. helveticus, and Pediococcus pentosaceus 25445, to inhibit thirty-five
strains of bacteria isolated from fish and fishery products were screened. Strains of
Enterococcus spp. and Flavobacterium/Cytophaga were inhibited by bacteriocins of LAB. Vibrio
parahaemolyticus was inhibited slightly by bacteriocins of L. plantarum 89 and P. pentosaceus
25445. Aeromonas hydrophila, Salmonella sp. and V. cholerae were not inhibited. The
bacteriocins of LAB are bactericidal to 42 to 54% of the fish microflora tested.
