Putative modes of accessing milk glycans in the infant gut by bifidobacteria. B. longum subsp. infantis captures intact HMO, while B. bifidum secretes extracellular enzymes prior to translocating lacto-N-biose degradation products. B. breve utilizes HMO monosaccharides cleaved by extracellular enzymes secreted by heterologous members of the consortium.
