Polylysine,(CAS#28211-04-3), 98.0%min. 1kg/bag
Epsilon Poly-L-lysine Introduction
CAS No.: 28211-04-3
ε-polylysine is a naturally produced, cationic homopolymer of 25-30 L-lysine(due to Streptomyces albulus fermentation.), which was connected by ε-amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine.

ε-polylysine Effect
1) ε-polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram+ bacteria which can’t easily inhibit by others.
2) As a good preservative, ε-PL is characterized as being high safety, water-soluble, stable at high temperatures, widely usage, non prejudice to the taste, antibacterial in neutral or subacidity conditions.
3) Because of the stability at high temperatures, it can inhibit some heat-resistant bacillus after heat treatment and sometadpole-form noncontractile siphovirus as well.
4) ε - PL can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the diet therapy for obese patients.
5) Besides, ε - PL also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc.
