Multimeric antimicrobial peptide expressed on cell surface

The present invention is the production of anti-bacterial microbial and anti-bacterial compositions and such antimicrobial microorganism comprising them expressing the present invention relates to polymer is antimicrobial peptide, the cell surface and the polymer, expressed it is cut by pepsin antimicrobial peptides which can be isolated as monomers there is provided a method. According to the present invention, to be administered directly in vivo by cell disruption, separation and microorganisms expressing them without having to go through the purification process on the cell surface of the antimicrobial peptide live state exhibit antimicrobial activity to produce antibacterial peptides, the antimicrobial peptide the cost of production significantly lowers the effect to induce bogeuphwa of antimicrobial peptides.
