A strain of Pediococcus acidilactici LAB 5 was isolated from vacuum-packed fermented meat product, in order to obtain a novel bacteriocin from food-grade organisms. Optimized culture conditions for bacteriocin production in different media (viz., MRS, TGE, TGE + buffer, TGE + Tween 80, and TGE + Tween 80 + buffer) and at different temperatures and pH conditions were reported. TGE + Tween 80 + buffer medium was found to be most effective for bacteriocin production (about 2400 AU/ml) by this strain, when incubated at 37 degrees C for 24 h. Bacteriocin, partially purified by adsorption-desorption method showed molecular mass of 10.3 kDa and produced prominent inhibition zone in activity gel. It showed significant storage stability both at high as well as in low temperatures for up to 6 months and retained its activity in a number of organic solvents, except in 2-mercaptoethanol. The treatment with amylase and lysozyme did not change its activity, but it lost its activity on proteinase K treatment. Antibacterial efficacy of bacteriocin was proved against some food spoilage and human pathogenic bacteria like Enterococcus, Leuconostoc, Listeria, Staphylococcus and Streptococcus.
