Probiotic potential and antimicrobial efficacy of a dairy isolate, Enterococcus faecium MBBL3.

ABSTRACT: Enterococcus faecium is a promising probiotic with potential antimicrobial effects. This study aimed to evaluate the probiotic and antimicrobial properties of E. faecium MBBL3, isolated from healthy cow milk, against bovine mastitis pathogens Klebsiella pneumoniae MBBL2 (Kp MBBL2) and Escherichia coli MBBL4 (Ec MBBL4), using comprehensive genomic and functional analyses. The genome assembly and functional annotations of MBBL3 unveiled many important probiotic traits, and comparative genomic analysis demonstrated its high degree of genetic similarity with other Enterococcus strains. MBBL3 exhibited the ability to ferment a diverse range of carbohydrates and possessed 76 genes linked to carbohydrate-active enzyme, including five key CAZy families with potential antimicrobial activity.
