Functions and mechanisms of bacteriocins produced by probiotics

Abstract:

Bacteriocins are ribosomally synthesized antimicrobial peptides produced by bacteria. Bacteriocin production has been considered an important trait in the selection of probiotic strains. Verified safe, they inhibit many food spoilage bacteria and pathogens. Besides, they facilitate the colonization of probiotics and regulate gut microbiota. In this article, we described the types of bacteriocins produced by probiotics, and the synthesis under specific conditions, functions, and mechanisms of them, hoping to enhance the understanding of functions and mechanisms of probiotics and lay a theoretical basis for the development of beneficial bacteriocins and probiotic products.
