Bacteriocin with activity against species of Lactobacillus, Lactococcus, Pediococcus, Leuconostoc and against B.subtilis and, to a lesser extent, against B.coagulans, B.cereus and species of Enterococcus, Listeria, Kocuria, Staphylococcus, Corynebacterium, Salmonella, Pseudomonas and Escherichia. Activity is stable between pH 2 and 12 at 25 degrees Celsius. Thermostable in a pH-dependent manner. Retains 100% activity after 15 minutes at 121 degrees Celsius at pH 4. Retained activity is lower when incubated at basic pH or pH 2. Antimicrobial activity is lost upon treatment with alpha-chymotrypsin, trypsin, pepsin and actinase E, but not when treated with proteinase K or endoproteinase Glu-C.
