Bacteriocin is a small molecule, produced by bacteria, that inhibits closely related strains. It is usually a peptide or a proteinâvarying sized chains of amino acids. These compounds are of interest both in studies of basic microbiology, and for the preservation of food and enhancement of human health. These toxins are produced by a wide range of bacteria. The first to be studied was that from escherichia coli, a bacterium that lives in human intestines and is frequently used in laboratory work. It produces a number of bacteriocins, with the most well-studied being the colicins.
