Bacteriocin with antibacterial activity against many strains of L.monocytogenes, L.seeligeri, L.welshimeri, L.grayi, L.murayi, L.ivanovii, L.innocus, C.divergens and C.piscocola. No antibacterial activity was detected against L.lactis, P.acidilactici, P.pentosaceus, L.salivarius, L.delbruekii, L.acidophilus, L.plantarum, L.casei, L.rhamnosus, S.thermophilus, P.freudenreichii, B.breve and E.coli. Displays a high degree of stability when incubated at temperatures of up to 121 degrees Celsius for 60 minutes. Has potential for use as a biopreservative for inhibiting L.monocytogenes in seafood products that do not usually undergo an adequate heat treatment. Belongs to the bacteriocin class IIA/YGNGV family.
