Bacteriocins: safe, natural antimicrobials for food preservation. – Semantic Scholar
Can’t read the image? J Food Process Technol. Bacteria have mechanisms to allow them to compete for nutrients and space in their habitat. One of these mechanisms are the acquisition of defense system as the production of antimicrobial peptides AMPsalso known by the name bacteriocins.
Bacteriocins are ribosomal synthesized peptides of less than 60 amino acids with a narrow to wide antimicrobial spectrum against gram positive bacteria. Antimiceobials are categorized in several ways, including producing strain, peptides structure, and mechanism of action.
Lactic acid bacteria LAB are generally recognizes as safe GRAS and producing bacteriocins with a broad spectrum of inhibition against the growth of spoilage and or pathogenic bacteria.
These bacteriocins offer potential applications in foods as natural preservatives that help reducing the addition of chemical preservatives or the intensity of heat treatments that affects food products quality antjmicrobials taste. Since food safety has become an increasingly important international concern, bacteriocins from lactic acid bacteria LAB that target food-borne pathogens without toxic or other adverse effects have received great attention.
