Product Details

Epsilon-polylysine CAS# 28211-04-3

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.Epsilon-polylysine is produced in Japan, and levels as low as 5 ppm have been found to be inhibitory, especially of some Gram-positive bacteria. It is water soluble, effective over a wide pH range, and is degraded to lysine by proteases.

Product Application of Epsilon-polylysine CAS# 28211-04-3

ε-Poly-L-lysine posess antimicrobial action stronger than alpha-Poly-L-lysine. Studies on the mode of action of ε-?PL suggest that adsorption of ε-?PL to the bacterial cell surface plays an important role in its antibacterial activity.A macromolecule composed of repeating L-lysyl units joined via 1,6-amide linkages.
