Has bactericidal activity against various Gram-negative Campylobacter, and the Gram-positive L.monocytogenes and B.subtilis. In vitro, inhibits C.jejuni strain ATCC 33560 (MIC=27.3 ug/ml). Stable between pH 4.0 and pH 8.0. Thermostable. Retains 100% activity after incubation at 60 degrees Celsius for 60 minutes and 15% after incubation at 121 degrees Celsius for 15 minutes. Antimicrobial activity is lost upon treatment with proteinase K, pronase, pepsin, trypsin, chymotrypsin and papain, but not when treated with catalase, lysozyme or lipase. Belongs to the bacteriocin class IIA/YGNGV family.
