'''Colicins''' are a type of bacteriocin - peptide and protein antibiotics released by bacteria to kill other bacteria of the same species, in order to provide a competitive advantage for nutrient acquisition <ref> PMID: 16166536 </ref>. Bacteriocins are named after their species of origin; colicins are so-called because they are produced by <i>E. Coli</i><ref>PMID: 17347522 </ref>. Because of their narrow killing spectrum which focuses primarily on the species which has made the peptide (or occasionally closely related species<ref> PMID: 12423779 </ref>), bacteriocins are important in microbial biodiversity and the stable co-existence of the bacterial populations<ref> PMID: 11792831 </ref><ref>PMID: 12110887 </ref>. | '''Colicins''' are a type of bacteriocin - peptide and protein antibiotics released by bacteria to kill other bacteria of the same species, in order to provide a competitive advantage for nutrient acquisition <ref> PMID: 16166536 </ref>.
