Characterization of dairy-related Bifidobacterium spp. based on their beta-galactosidase electrophoretic patterns.


Numerical analysis of phenotypic characteristics based on enzymatic activity and carbohydrate fermentation allowed the discrimination of most strains of bifidobacteria of animal origin from those of human origin. Strains of bifidobacteria studied were separated into nine groups based on numerical analysis. Three groups contained most strains of animal… (More)
