      乳酸鏈球菌素(Nisin)亦稱乳酸鏈球菌肽或音譯為尼辛，是乳酸鏈球菌產(chǎn)生的一種多肽物質(zhì)，由34個氨基酸殘基組成，分子量約為3500 Da。由于乳酸鏈球菌素可抑制大多數(shù)革蘭氏陽性細菌，并對芽孢桿菌的孢子有強烈的抑制作用，因此被作為食品防腐劑廣泛應用于食品行業(yè)。食用后在人體的生理pH條件和α-胰凝乳蛋白酶作用下很快水解成氨基酸，不會改變?nèi)梭w腸道內(nèi)正常菌群以及產(chǎn)生如其它抗菌素所出現(xiàn)的抗性問題，更不會與其它抗菌素出現(xiàn)交叉抗性，是一種高效、無毒、安全、無副作用的天然食品防腐劑。

Introduction

Nisin (also known as Nisina, Nisine, Nisaplin) is a polypeptide with 34 amino acid residues widely used as a food preservative. Nisin possesses anti-microbial activity against a wide range of Gram-positive bacteria and their spores in food. It is catabolized to amino acid in human body, so it is no harm or vice-effect to people. Extensive micro-biological tests have not shown any cross resistant between Nisin and medical antibacterial drug. It is a natural food preservative which is highly efficient, safe and has no side-effects. In addition, it has excellent solubility and stability in food.
