Description

Product Introduction

Polylysine is a natural antimicrobial peptide composed of lysine linked by peptide bonds, with broad-spectrum bacteriostatic effects, commonly used in food preservation and other fields.

Product Application

(1) Food industry: As a natural preservative, it is widely used in meat products, dairy products, beverages, pastries, etc., to inhibit the growth of microorganisms such as bacteria and molds, and extend the shelf life of food.

(2) Pharmaceutical field: Due to its antibacterial properties, it can be used for disinfection of some medical devices or as a pharmaceutical excipient to assist antibacterial drugs in functioning.

(3) Daily chemical products: Added to cosmetics and skin care products, it helps inhibit harmful microorganisms and maintain product stability.

(4) Agricultural field: It can be used as a component of biological pesticides to inhibit pathogenic bacteria on crops, reduce the use of chemical pesticides, and contribute to green agriculture.

(5) Feed processing: Adding it to feed can inhibit the reproduction of harmful microorganisms, prevent feed spoilage, and may also help improve animal intestinal health.

Product Function

(1) Broad-spectrum antibacterial activity: It can effectively inhibit the growth and reproduction of various bacteria (such as Escherichia coli, Staphylococcus aureus, etc.), molds, yeasts and other microorganisms, with a relatively wide range of action.

(2) Extending shelf life: By inhibiting microbial activities, it delays the spoilage of food, feed, daily chemical products, etc., and prolongs their storage time.

(3) High safety: As a natural peptide substance, compared with some chemical preservatives, it has better biocompatibility and poses less potential harm to humans and the environment when used within a reasonable range.

(4) Auxiliary regulatory effect: In the pharmaceutical and feed fields, it may help enhance the antibacterial effect or improve the intestinal microenvironment, indirectly playing a role in maintaining health.

ECHEMI Editorial Reference

from Streptomyces albulus.
A peptide which is a homopolymer of lysine.
ε-Polylysine is a light yellow powder with strong hygroscopicity and slightly bitter taste. It is a linear polymer of lysine. It is produced by streptomyces fermentation and has a broad-spectrum antibacterial effect. ε-polylysine is polymerized by 25-30 lysine groups, which is relatively stable to pH and heat. Its antibacterial effect is related to the degree of polymerization and the environment. The molecular weight of polylysine is between 3600-4300 which has the best antibacterial activity.
In 1977, Japanese scholars S. Shima and H. Sakai, in the process of screening Dragendo~Positive (DP) substances from microorganisms, discovered that a strain of actinomycete No.346 can produce a large amount of stable DP substances. The analysis and structural analysis of the hydrolysate confirmed that the DP substance is a homopolymer of 25-30 lysine residues. A homologous amino acid polymer formed by NH2 condensation, so it is called ε-Poly-L-lysine (ε-Poly-L-lysine for short ε-PL).
ChEBI: A macromolecule composed of repeating L-lysyl units joined via 1,6-amide linkages.
