Gram-positive bacteria inhibitor Streptococcus lactis peptide

Product Description

Nisin E234 CAS 1414-45-5

Nisin (Streptococcus lactis peptide)

Nisin, also known as Streptococcus lactis peptide, is a polypeptide produced by Streptococcus lactis, consisting of 34 amino acid residues with a molecular weight of approximately 3,500 Da. It effectively inhibits most Gram-positive bacteria and demonstrates strong inhibitory effects on Bacillus spores, making it widely used as a food preservative in the food industry.

Under physiological pH conditions in the human body and through the action of α-pancreatic rennet protease, nisin can be hydrolyzed into amino acids. It does not disrupt normal intestinal flora, does not create resistance issues like other antimicrobials, and exhibits no cross-resistance with other antimicrobial agents, establishing it as an efficient, non-toxic, safe natural food preservative with no side effects.

Key Benefits

Effective against a wide range of Gram-positive bacteria
Strong inhibitory effect on Bacillus spores
Natural and safe food preservative
No impact on human intestinal flora
No cross-resistance with other antimicrobials

Target Industries & Applications

Food and beverage industry, particularly in the preservation of dairy products, canned goods, and processed foods.
