Garvicin KS (garKS)

GarKS is a multipeptide bacteriocin composed of three small similar peptides with a size between 32 and 34 amino acids. Potent activity against many pathogenic Gram-positive bacteria (Listeria, Enterococcus, Bacillus, and Staphylococcus), representing a great potential for antimicrobial applications.
