Nisin primarily exerts its antimicrobial effects by disrupting the integrity of bacterial cell membranes. It is a natural antimicrobial peptide produced by Lactococcus lactis and has a broad spectrum of antimicrobial activity, particularly effective against Gram-positive bacteria.

The specific mechanism of action involves nisin interfering with the normal functions of the bacterial cell membrane, increasing its permeability, which causes the leakage of essential intracellular substances like potassium ions, amino acids, and nucleotides. It also disrupts cell wall synthesis, compromising membrane integrity. This disruption ultimately leads to cell lysis and bacterial death, achieving its antimicrobial effect.

Due to its natural, safe, and residue-free characteristics, nisin is widely used in food preservation, such as in dairy products and meat products, to extend shelf life and maintain product quality. Nisin also has potential applications in the medical field, although its weaker activity against Gram-negative bacteria somewhat limits its use in certain areas.

Nisin's ability to inhibit or kill bacteria by disrupting membrane integrity gives it broad application prospects in both food preservation and medical fields.
