[Data] Antibacterial effects of Polylysine against various microorganisms.
Natural amino acid 'Polylysine' is used as an additive in food preservatives, hygiene materials, and daily necessities. Introducing the antibacterial effects of polylisine against various microorganisms.
ε-Polylysine (hereafter referred to as Polylysine) is a substance formally known as ε-Poly-L-lysine. It is a homopolymer consisting of 25 to 35 units linked by amide bonds, formed from the ε-amino group and the α-carboxyl group of the essential amino acid L-lysine. Since 1989, it has over 30 years of manufacturing history and is widely used as a food preservative amino acid. We will introduce the minimum inhibitory concentration (MIC) of Polylysine against various microorganisms. Polylysine exhibits antibacterial effects at concentrations ranging from a few ppm to several hundred ppm, regardless of the type of bacteria, yeast, or mold. *For more details, please download the PDF or feel free to contact us.
