Also known as :ε-Poly-L-Lysine hydrochloride, ε-Poly-L-Lysine HCl, Polylysine HCl, epsilon polylysine HCl, epsilon poly-L-Lysine HCl,
ε-poly-L-lysine or ε-polylysine is a new food biopreservative compared with natamycin and nisin. This ingredient is a natural antimicrobial peptide metabolized by Streptomyces and has a wide antibacterial spectrum against Gram-negative, Gram-positive bacteria, yeasts, and molds. Commonly used in the preservation of rice, soups, noodles and sliced fish. ε-poly-L-lysine is base form, and ε-poly-L-lysine HCl is acid form. it acutally same biological function. Solubility of HCL form is better for commerical application.
ε-polylysine is a highly polymerized polyvalent cation (positively charged)
which interacts and binds with negatively charged microbial cell membranes
of microorganisms and form holes in the membrane.
it destroys the cell membrane structure of microorganisms and causes the leakage of intracellular substances.
ε-polylysine enters the cell through the holes in the membrane, which affects the structure and function of the cell membrane, and interferes the normal physiological metabolism of microorganisms, destroys the transmission of materials and energy in the cell, induces the cell to autolysis and finally causes the death of the bacterial cell. It has the antibacterial effects on following microorganisms list (incomplete):
