Biological preservation of foods–Bacteriocins of lactic acid bacteria
نویسندگان
چکیده
Lactic acid bacteria and their antimicrobial metabolites have potential as natural preservatives to control the growth of spoilage and pathogenic bacteria in foods. To date, nisin is the only bacteriocin that has found practical applications in some industrially processed foods. Its antibacterial activity and possible use as a biopreservative has been studied in a large number of food systems. Its application for the control of some pathogens and food spoilage organisms has been approved in a number of countries. Limited studies have shown that pediocins from several Pediococcus strains can also be used effectively in food systems to control Listeria monocytogenes. This review discusses the potential of lactic acid bacteria and their principal antimicrobial peptides, bacteriocins in biological preservation of foods. It is anticipated that the advances in bacteriocins research and combination treatments for food preservation will benefit both the consumer and the producer.

Bacteriocins as a natural antimicrobial agent in food preservation: A review
Bacteriocins are ribosomally synthesized peptides or proteins with antimicrobial activity, produced by different groups of bacteria. Many lactic acid bacteria (LAB) produce bacteriocins with rather broad spectra of inhibition. Though these bacteriocins are produced by LAB found in numerous fermented and non-fermented foods, nisin is currently the only bacteriocin widely used as a food preservat...

متن کاملPreservation and fermentation: past, present and future.
Preservation of food and beverages resulting from fermentation has been an effective form of extending the shelf-life of foods for millennia. Traditionally, foods were preserved through naturally occurring fermentations, however, modern large scale production generally now exploits the use of defined strain starter systems to ensure consistency and quality in the final product. This review will...
