I. Mechanism of Freeze-Drying on Nisin Activity As a polypeptide with 34 amino acids, Nisin's activity relies on the rigid structure formed by 5 intramolecular disulfide bonds. Activity loss during freeze-drying m...

I. Foundation of Process Optimization: Ultrasonic Extraction Principles and Nisin Characteristics Nisin, a polypeptide antibiotic secreted by Streptococcus lactis, has a molecular weight of approximately 3.5 kDa, ...

Nisin is a small peptide synthesized and secreted by Lactococcus lactis during metabolism, composed of 34 amino acids with strong bactericidal effects, effectively inhibiting the growth of Gram-positive bacteria. The fol...

As a natural antibacterial peptide, Nisin features strong water solubility but poor lipid solubility, with stability susceptible to environmental factors (e.g., gastric acid, enzymatic hydrolysis). Liposome carrier syste...

I. Application Background of Electrospray Drying Technology in Nisin Preparation As a natural antibacterial peptide, the biological activity of Nisin (nisin) is susceptible to high temperature, oxidation, and inte...

I. Core Directions for Fermentation Process Improvement Nisin, a natural antibacterial peptide produced by Lactococcus lactis fermentation, requires multi-dimensional optimization of strain characteristics, medium...
