Abstract

Lactococcus lactis subsp. diacitilactis S50 produces a bacteriocin, designated bacteriocin S50, which has a narrow antibacterial spectrum. It was active only against Lactococcus species, including a nisin producer exhibiting a bactericidal effect. The activity of bacteriocin S50 was sensitive to proteases. It retained antimicrobial activity after being heated to 100°C for up to 60 min and in the pH range 2 to 11.
