Abstract

This research was conducted to know the effectiveness of filtrate bacteriocin Lactobacillus acidophilusaccording to concentrations toward zone of growth inhibition contaminant bacteria from swordfish(Auxis rochei)stew. This research was an experimentally research conducted in laboratory of Food Chemical Research Center of LIPI Bandung used completely randomized design with two replications. Species of contaminant bacteria used wereBacillus sp. (RR2) (Da, Te, Amp, Sxt), Staphylococcus aureus(R4) and Staphylococcus aureus (R5) (Da) witha range of concentration the filtrate bacteriocin culture L.acidophilus50, 60, 70, 80, 90 and 100%. The parameters were diameter (mm) of the zones of bacterial growth inhibition.The Results showed that treatment with filtrate of bacteriocin concentration 50 to 100% effective can inhibition the growth of bacterial contaminants. This treatment privide that the filtrate bacteriocin of culture L.acidophilus can be used as bio-preservativein the swordfish stew.
