Novel antimicrobial peptide designed from duck-derived antimicrobial peptide anduse thereof

Abstract

The present disclosure relates to a new peptide and, more specifically, to a new peptide prepared by means of substitution or/and deletion of some amino acid sequences of a duck-derived antimicrobial peptide, and a use thereof. The novel peptide according to the present disclosure has excellent antimicrobial activity against gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Acinetobater baumannii; gram-positive bacteria such as Staphylococcus aureus, Listeria monocytogenes, and Bacillus cereus; and antibiotic-resistant bacteria, and therefore, as a material having antimicrobial activity, the novel peptide can be useful as a material for coating, packaging, preservatives (cosmetic preservatives, food preservatives, pharmaceutical preservatives), and additives (food additives, cosmetic additives, feed additives), as well as for antibiotics, pharmaceuticals, cosmetics, food, feed, and biopesticides. In particular, the novel peptide of the present disclosure has minimal cytotoxicity and has the advantage of being safe for the human body even for long-term use.
