An antibacterial substance, such as colicin, that is produced by certain bacteria and kills or inhibits the growth of closely related species or other strains within the same species.
protein produced by certain species of bacteria that, by inducing metabolic block, are toxic to related strains of those bacteria. Also called protein antibiotic.

a peptide produced by some strains of bacteria which inhibits the growth of, or kills, other bacteria. Examples are staphylococcin, produced by Staphylococcus aureus, and colicins, produced by Escherichia coli.
