BIFIDOGENIC AND BUTYROGENIC EFFECTS OF INULIN-TYPE FRUCTANS AND ARABINOXYLANS

Bifidobacteria are important members of the human gut microbiota. They are capable to degrade inulin-type fructans (ITF; oligofructose and inulin) and arabinoxylan-oligosaccharides (AXOS), non-digestible polysaccharides (NDPs) present in the human diet. However, these properties are strain-dependent, as they rely on the expression of the appropriate enzymes. Concerning ITF degradation, four phenotypical groups of strains can be distinguished...
