The two-synergistic peptide bacteriocin produced by Enterococcus faecium NKR-5-3 isolated from Thai fermented fish (Pla-ra)



The two-synergistic peptide bacteriocin produced by Enterococcus faecium NKR-5-3 isolated from Thai fermented fish (Pla-ra)



ScienceAsia 30(2): 115-122



Bacteriocin produced by Enterococcus faecium NKR-5-3 isolated from Thai fermented fish was characterized and purified. According to its physical and chemical properties, E. faecitun NKR-5-3 produced heat tolerant bacteriocin with broad spectrum activity against indicator strains. Treatment of bacteriocin in cell-free neutralized supernatant (CFNS) with some proteases eliminated or reduced its activity, suggesting it is proteinaceous.
