Explore our high-purity chemical raw materials, bio-preservatives, and fine specialty compounds engineered for global industrial applications.
In the era of clean-label consumer mandates, green industrial chemistry, and strict biocide regulations, Streptomyces albulus polylysine (commercially known as ε-Polylysine or epsilon-poly-L-lysine, CAS No. 28211-04-3) has emerged as a paramount bio-based antimicrobial polymer. Unlike traditional synthetic chemical preservatives such as parabens, sodium benzoate, and sorbic acid—which often face stringent regulatory scrutiny, cytotoxicity concerns, and limited pH operational windows—ε-Polylysine synthesized via Streptomyces albulus aerobic fermentation delivers broad-spectrum, non-toxic, and thermal-stable microbial inhibition.
Potent against resistant pathogens including Escherichia coli, Staphylococcus aureus, Listeria monocytogenes, Bacillus subtilis, and common spoilage molds at remarkably low minimal inhibitory concentrations (MIC 1–50 ppm).
Maintains structural integrity and antimicrobial potency during high-temperature thermal processing (autoclaving at 121°C for 30 min, pasteurization) and across an extensive pH spectrum (pH 2.0 to 9.0).
Fully biodegradable. Upon ingestion or environmental exposure, ε-Polylysine undergoes enzymatic cleavage into L-lysine—an essential amino acid—yielding zero toxic metabolites or bioaccumulation risks.
Understanding the metabolic pathways of Streptomyces albulus and the electrostatic mode of action against cellular pathogens.
Industrial production utilizes optimized mutant strains of Streptomyces albulus (such as S. albulus strain M-Z18 or specialized high-yield industrial variants) cultivated in aerated fermenters under precise dissolved oxygen (DO), carbon-to-nitrogen ratios, and controlled acidic pH conditions (pH 3.8–4.2).
The antibacterial activity of ε-Polylysine stems from its high density of positively charged free amino groups (NH3+) at physiological and acidic pH levels.
JIMPOCHEM enforces high quality control standards for Streptomyces albulus derived polylysine. Every production lot undergoes rigorous HPLC, FT-IR, heavy metal mass spectrometry, and microbiological testing.

Analyzing worldwide supply chains, market drivers, and regional adoption dynamics for biosourced preservatives.
As the pioneer of industrial bio-fermentation, the APAC region leads both production capacity and domestic consumption. China has established integrated supply chain infrastructure, significantly reducing manufacturing costs while elevating purity levels for export to global markets.
Driven by strict FDA GRAS notices and rising consumer demand for "free-from-synthetic" labels, North American food processors are substituting classical preservatives with ε-Polylysine in ready-to-eat meats, cooked rice products, and organic beverages.
With EFSA evaluations confirming safety profiles, EU cosmetics and specialty chemical formulators are adopting ε-Polylysine as an eco-friendly booster for broad-spectrum anti-microbial preservation in water-based personal care matrices.
Detailed dosing guidelines, synergistic combinations, and functional performance across key industrial sectors.
