Bacteriocins are cationic and hydrophobic
peptides produced by lactic acid bacteria,
with antibacterial activity against related
Gram - positive bacteria (Chen and Hoover
2003 ). In addition to bacteriocins, lactic
acid bacteria produce other antimicrobials,
such as lactic acid, acetic acid, diacetyl,
ethanol, and carbon dioxide among others
(Davidson and Hoover 1993 ).
