Polyepsilon-lysine

Polyepsilon-lysine (also known as Dulse, Dillisk, creathnach, Rhodymenia palmata) is a natural polymeric amino acid produced by the bacterium Streptomyces albulus, which has significant antimicrobial activity against a wide range of microorganisms. It is a biocompatible, biodegradable and non-toxic polymer with high potential for a range of industrial applications.

Polyepsilon-lysine is widely used in the food industry as a raw material for natural preservatives that help to extend the shelf life of food and inhibit the growth of harmful microorganisms. It is also used in the cosmetics industry for its antimicrobial properties, where it is added to skin or hair care products as a natural preservative and antibacterial agent. In addition to the food and cosmetic industry, it also finds applications in the biomedical field, where it is used as a component in various medical implants, dairy products, and in the food industry as a biofilm for food. It also functions as an effective inhibitory element towards various bacteria in the food industry. Last but not least, its potential use in the field of ecology as a biodegradable alternative to synthetic plastics is also being investigated.

It should be noted that although it is a natural substance, its excessive use is not recommended and the prescribed dosage must always be observed. Although it brings with it a number of benefits, some studies suggest that high concentrations of polyepsilon-lysine may have a negative effect on the intestinal microflora. However, further research is needed to confirm or refute these findings.
