Nisin

Nisin is manufactured from the fermentation of a milk-based medium by Lactococcus lactis subsp. lactis. The nisin from this fermentation is concentrated, dried and standardized with sodium chloride to produce Nisin, which has a known and consistent level of nisin activity. Nisin natural antimicrobial is used to control bacterial spoilage in both heat processed and low pH foods. Nisin is effective against a wide range of Gram-positive bacteria and is particularly effective against the heat-resistant spores produced by Gram-positive Bacillus and Clostridium spp. Nisin has no effect against Gram-negative bacteria, yeasts or moulds.
