Impact of bacteria possessing extracellular or intracellular GH95 fucosidases on the prebiotic effects of 2′-FL. In responders, the increased abundance of bacteria possessing extracellular fucosidases could provide an environment rich in fucose and lactose available to Blautia. By contrast, an increased abundance of bacteria possessing intracellular fucosidases which directly take up and use considerable amounts of 2′-FL could result in an insufficient supply of fucose and lactose to Blautia in non-responders. 2′-FL, 2′-fucosyllactose.
