Inhibitory efficacy, production dynamics, and characterization of postbiotics of lactic acid bacteria.

ABSTRACT: Antimicrobial resistance (AMR) poses a significant threat to human health and food safety. Lactic acid bacteria (LAB) produce bioactive compounds, known as postbiotics, that act as promising natural preservatives with broad-spectrum antimicrobial activity. This study aimed to evaluate the antimicrobial spectrum, production dynamics, and physicochemical properties of postbiotics derived from five LAB strains: Lactobacillus plantarum NBRC 3070, Lactobacillus acidophilus ATCC 4356, Lactobacillus casei ATCC 393, Lactobacillus rhamnosus GG ATCC 53103, and Bifidobacterium animalis subsp. lactis ATCC 27673. The antimicrobial activity of these postbiotics was assessed against several Gram-positive and Gram-negative pathogens. A crude bacteriocin-like inhibitory substance (BLIS), a postbiotic compo
