Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Many lactic acid bacteria (LAB) produce a high diversity of different bacteriocins. Though these bacteriocins are produced by LAB found in numerous fermented and non-fermented foods, nisin is currently the only bacteriocin widely used as a food preservative.
Strains of Enterococcus faecalis produce a bacteriocin with activity against the pneumococcal bacteria that cause pneumonia. Escherichia coli, a bacterium that lives in human intestines, produces a number of bacteriocins.Probiotics aid in digestion, and prevent harmful bacteria from proliferating inside the body.hese 10 animal facts will amaze you. 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.
