Bacteriocin that inhibits the growth of closely related Enterococcus species and a wide range of Gram-positive bacterial species. Inhibits the growth of several strains of the Gram-negative bacterium E.coli, but not the growth of Gram-negative Pseudomonas species. Stable at pH 5.0. Thermostable, retains activity after heating at 60, 80 and 100 degrees Celsius for 1 hour. Long-term storage at 4 degrees Celsius or -20 degrees Celsius does not affect activity. Belongs to the bacteriocin class IIA/YGNGV family.
