Lactolisterin BU-producer Lactococcus lactis subsp. lactis BGBU1-4: Biocontrol of Listeria monocytogenes and Staphylocococcus aureus in fresh soft cheese and effect on immunological response of rats

摘要

In last two decades, there has been a strong trend in the application of lactic acid bacteria as adjunctive cultures to control growth of spoilage and pathogenic bacteria in food. One of the most important properties that contribute to the application of these bacteria is the production of antimicrobial molecules. Lactococcus lactis subsp. lactis BGBU1-4, isolated from traditional brined cheese, produces thermostable bacteriocin named lactolisterin BU, with broad spectrum of activity against spoilage bacteria and foodborne pathogens.
