High antibacterial activity of lactic acid bacteria against food-borne pathogens

Abstract:

Food-borne pathogens threaten human life and health and antibiotics are the most effective choice at the moment.However,the irregular use of antibiotics has led to the rising prevalence of drug-resistant bacteria.Lactic acid bacteria are recognized as safe food-grade microorganisms.They boast good application prospects attributing to the functions of antagonizing pathogenic bacteria,improving immune regulation,strengthening intestinal barrier,and balancing intestinal microbiota.They are expected to become the next generation of safe,stable,and economical biological antibacterials to reduce or even replace antibiotics.This article describes the antibacterial substances,antibacterial mechanisms,and antibacterial functional properties of lactic acid bacteria to promote the research on and application of them.
