Epsilon-polylysine CAS 28211-04-3 ε-PL

ε-Polylysine is light yellow powder, strong hygroscopicity, slightly bitter taste, is a straight chain polymer of lysine, which is produced by the fermentation of Streptomyces, and has a broad-spectrum bacteriostatic effect. ε-Polylysine is made of 25-30 lysine groups polymerization, it is more stable to ph, heat, and its bacteriostatic effect is related to the degree of polymerization and the environment, and the molecular weight of the molecular weight is the best in the range of 3600-4300 bacteriostatic activity.
