ε-Poly-L-lysine (MW 3800-4200)
Based on 1 Customer Validation
Epsilon-polylysine is an antimicrobial peptide that can be produced by bacteria such as Streptomyces. Epsilon-polylysine inhibits the growth of microorganisms such as bacteria, yeasts and molds and is therefore often used as a green food additive and preservative in various food and beverage products. Epsilon-polylysine has a variety of properties, including thermal stability, resistance to acidic conditions, and broad-spectrum antimicrobial activity. Epsilon-polylysine can be loaded on other materials to form nanoparticles or form nanofiber membranes for targeted delivery to exert sustained antibacterial efficacy. Epsilon-polylysine is also used as a liposome stabilizer.

Biological Activity
ε-Poly-L-lysine (MW 3800-4200) (1000, 2000 and 4000 mg/L; 20 μL was added to the wound at the equator of each jujube fruit, after air-drying at room temperature for 1 hour, the treated fruits were placed in a plastic box filled with sterile water, maintained at 95% humidity, and stored at 22°C for 0-72 h) dose-dependently reduces the disease severity of gray mold in jujube fruit[5]. ε-Poly-L-lysine (MW 3800-4200) (0-450 mg/L; 1-4 days) dose-dependently inhibites the growth of B. cinerea hyphae[5].
