Nisin

CAS No.:

1414-45-5

Other Name:

nisin from streptococcus lactis

Appearance:

Description:

Nisin 1000IU is a polycyclic antibacterial peptide produced by the bacterium Lactococcus lactis that is used as a food preservative. It has 34 amino acid residues, including the uncommon amino acids lanthionine, methyllanthionine, didehydroalanine, and didehydroaminobutyric acid. These unusual amino acids are introduced by posttranslational modification of the precursor peptide. In these reactions a ribosomally synthesized 57-mer is converted to the final peptide. The unsaturated amino acids originate from serine and threonine, and the enzyme-catalysed addition of cysteine residues to the didehydro amino acids result in the multiple thioether bridges. Vegetal Nisin inhibits spoilage microorganisms including lactic acid spoilage bacteria, thus helping to prolong shelf-life and retain food quality. It has also been used increasingly as a primary intervention to inactivate or inhibit the outgrowth of pathogenic food microorganisms such as Listeria, Staphylococcus, and Mycobacterium, and the spore-forming bacteria, Bacillus and Clostridium, thereby helping to increase food safety.
