The identification of bacteriocin with a wide activity spectrum as a consequence of bacterial infections and spoilage microorganisms addresses an important aspect of food safety. In this study, the potential bacteriocin-producing bacterium was preliminarily confirmed as Enterococcus species and the isolate was identified as Enterococcus casseliflavus MI001. The probiotic properties of E. casseliflavus MI001 was studied for acid and bile tolerance tests. In addition, the aggregation and co aggregation ability of the strain to protect the host from colonization was studied. Further, the strain was also found antibiotic susceptibile against commonly available antibiotics.
