Lactococcal bacteriocins: getetics and mode of action

Lactic acid bacteria produce a variety of antimicrobial substances which are important in food fermentation and preservation. Apart from metabolic end products such as hydrogen peroxide, diacetyl and organic acids, some species secrete bactericidal substances of proteinaceous nature, which are termed bacteriocins. Althought bacteriocins of lactic acid bacteria have been the subject of many studies, relatively little is known about their chemical structure, their mode of action, and their genetic determinants. ...
