Poly-ε-lysine (ε-PL) is a non-toxic biopolymer with antimicrobial properties. The production of
ε-PL by Streptomyces noursei NRRL 5126 shake-flask culture was optimized by identifying …

Poly‐ε‐L‐lysine is a natural homo‐polyamide of L‐lysine with excellent antimicrobial
properties, which can be used as a novel preservative and has a wide range of applications …

The enhancement of ε-poly-l-lysine (ε-PL) production by Streptomyces albulus strain no. 410
(S410) by means of a pH control strategy was investigated. S140 cells produce ε-PL at a …

Response surface methodology (RSM) were employed to study the effect of yeast extract,
glucose, ammonium sulfate, and initial medium pH on the production of poly-ɛ-lysine (ɛ-PL) …

The goal of this study was to increase ε-Poly-L-Lysine (ε-PL) production by Streptomyces sp.
M-Z18 through optimization of the culture medium. Glycerol,(NH4) 2SO4 and K2HPO4 were …

To improve the efficiency of ε-poly-l-lysine (ε-PL) production by Streptomyces sp. M-Z18,
batch and fed-batch fermentations with glucose and glycerol (co-fermentations) were …

Poly‐ε‐lysine produced by streptomyces species is a promising biopolymer owing to its
antimicrobial activity and safety for humans. A number of nutritional factors influencing poly …

Abstract ε-Poly-L-lysine (ε-PL) is a homopolymer of L-lysine molecules connected between
the epsilon amino and alpha carboxyl groups. This polymer is currently used as a natural …

Abstract ε-Poly-l-lysine (ε-PL), as a food additive, has been widely used in many countries.
However, its production still needs to be improved. We successfully enhanced ε-PL …

Abstract ε-Poly-l-lysine (ε-PL)—a natural food preservative with wide antimicrobial activity
and high food safety—is increasingly attracting widespread attention. However, the high cost …
