Uses

An antibiotic with bactericidal action

Purification Methods

This polypeptide from S. lactis is purified by crystallisation from 80% (v/v) EtOH and by countercurrent distribution. The synthetic polypeptide antibiotic can also be purified by preparative HPLC and assayed by HPLC on a Nucleosil 3007C18 (6 x 250mm) column using a MeCN—0.01M HCl gradient (30-50%), at 2%/minute, and flow rate of 1.5mL/minute to give a retention time of 8.1 minutes; or MeCN—0.3M guanidine-HCl gradient (30-50%), at 2%/minute, and flow rate of 1.5ml/minute to give a retention time of 10.9minutes. FAB-MS gave the pseudomolecular ion m/z at 3352.7 (M + H)+. It is soluble in dilute acid and is stable even on boiling. [Berridge et al. Biochem J 52 529 1952, synthesis by Fukase et al. Tetrahedron Lett 29 795 1988.]

Description

As a ribosomally synthesized peptide, Nisin has broad-spectrum antibacterial activity that is produced by the Lactococcus lactis. In the food industry, Nisin is obtained from the cultivating of Lactococcus lactis on natural substrates, such as milk or dextrose. It serves as a natural, antibacterial, and toxicologically safe food preservative which is protect against many bacteria that are food-spoilage pathogens. As a food additive, Nisin is popularly used in food production, such as milk, meats, fast food, beverages, health care products and medicines, etc. It is effective to decrease sterilization time, lower temperature during food sterilization, improve food quality, lessen damage to nutrition, and extend shelf life by suppressing Gram-positive spoilage and pathogenic bacteria. Besides, it has been studied as a possible treatment for infections of Clostridium difficile combined with miconazole. It was originally isolated in the late 1930s and approved as an additive for food use in the USA in the late 1960s.
Nisin functions by binding to cell wall precursor lipid components of bacteria and disrupts cell wall production. Once introduced Nisin initially blends with Lipid II, a precursor molecule used to form bacterial cell wall, to create a complex. The complex penetrates the cell wall and breaks into the cytoplasmic membrane and form pores, through which the internal cytoplasmic content oozes out leading to bacterial inhibition or death.

Definition

ChEBI: A type-A lantibiotic containing 34 amino acid residues (including lanthionine (Lan), methyllanthionine (MeLan), didehydroalanine (Dha) and didehydroaminobutyric acid (Dhb)) and five thioether bridges. It is obtained by fermentation of the bacterium L ctococcus lactis and shows particular activity against Clostridium botulinum. It is used in the production of various processed foods to suppress Gram-positive spoilage and pathogenic bacteria and so extend shelf life.
