Genomic Discovery of Taxon-Specific Molecular Markers for Lactobacillaceae Genera

Background: Members of the family Lactobacillaceae, comprising 36 genera, play vital roles in food fermentation (e.g., wine, yogurt, and cheese production) and contribute significantly to human health through their probiotic properties. Despite their importance, species from different genera are primarily distinguished by phylogenetic clustering and genomic similarity matrices, and no consistent molecular, biochemical, or physiological traits …
