 Nisin (CAS NO.1414-45-5) is used in processed cheese, meats, beverages, etc. during production to extend shelf life by suppressing Gram-positive spoilage and pathogenic bacteria and it is used as a food additive.

 Nisin is produced by fermentation using the bacterium Lactococcus lactis. Commercially, it is obtained from the culturing of Lactoccus lactis on natural substrates, such as milk or dextrose, and is not chemically synthesized.

When heated to decomposition it emits acrid smoke and irritating fumes.
