BACTERIOCINS OF LACTIC ACID BACTERIA: MECHANISMS OF ACTION AND ANTIMICROBIAL ACTIVITY AGAINST PATHOGENS IN CHEESE
Two possible mechanisms for the beneficial effects of lactic acid bacteria on gastrointestinal disturbances are: i) production of antimicrobial compounds such as lactic acid and bacteriocins, and ii) adherence to the mucosa and co-aggregation to form a barrier that prevents colonization by pathogens.
Lactic acid bacteria have also been used in probiotic food, as they produce bacteriocins that inhibit harmful bacteria [10].
