Antimicrobial Peptide Nisin Supply Price

Nisin, also known as lactococcin or simply nisin, is a well-known representative of antimicrobial peptides (AMPs). What are antimicrobial peptides? These are small polypeptides with broad-spectrum antimicrobial activity, widely found in nature, including in bacteria, fungi, plants, and animals. These peptides can disrupt bacterial cell membrane structures or inhibit cell wall synthesis, effectively killing or inhibiting the growth of various pathogenic microorganisms.

Nisin is produced by Lactococcus lactis through a ribosomal synthesis mechanism during its metabolic process. It is a small polypeptide composed of 34 amino acid residues. Nisin is harmless to humans and has good thermal stability, allowing it to maintain its activity during food processing. It exhibits strong inhibitory effects against various Gram-positive bacteria, such as Listeria and Staphylococcus aureus, making it widely used in food preservation and protection.

As an outstanding representative of antimicrobial peptides, nisin boasts advantages such as high efficiency, non-toxicity, and no residues. Additionally, its unique antibacterial mechanism makes it less likely to induce resistance in pathogenic bacteria, thus holding significant value in food safety and public health. Moreover, with further research, nisin has also shown promising applications in medicine and agriculture.

Therefore, nisin is a very important member of the antimicrobial peptide family. Its unique properties and application value make it a focal point in antimicrobial peptide research and application.
