Synergistic Effect of Physico-chemical Treatment and Bacteriocin Produced by Enterococcus faecium MJ-14

When L. monocytogenes () at exponential phase cells were heated for 5 min at in the presence of the bacteriocin (30 BU/mL) produced by E. faecium MJ-14, the number of viable cells was markedly reduced at p ), while it was reduced by 1.1 log unit only under single treatment of the bacteriocin after 12 k at . The addition of the bacteriocin (300 BU/mL) into skim milk inoculated with L. monocytogenes (CFU/mL) reduced the cells by 1.5 log unit, in case of the cell suspension stored at for 24 hr. Moreover, L. monocytogenes was reduced by 2 log unit when stored at for 7 days in gound pork added with 300 BU/mL of 린e bacteriocin.
