Bacteriocin that inhibits the growth of several Gram-positive bacteria, especially the food-borne pathogens L.monocytogenes, B.cereus strain ATCC 11778, B.cereus strain ATCC 21366, B.cereus strain ATCC 10876 and B.cereus strain ATCC 14579. Likely to act by disrupting the pathogen membrane resulting in leakage of intracellular constituents. Does not inhibit the growth of Gram-negative bacteria. Active from pH 3.0 and pH 9.0. Thermostable, retains activity after heating at 50 degrees Celsius for 24 hours. Activity decreases over 70 degrees Celsius. Belongs to the bacteriocin class V family.
