PW, peptone water. 1, Rats associated with C. butyricum DSM10702; 2, rats associated with a human faecal microbiota; 3, α-GOS-enriched soy milk (see 4 and 5) was added with a 5 % (v/v) coffee bean α-Gal solution at 1 IU/ml and was incubated for 12 h at 37°C; 4, the concentrations of raffinose and stachyose in the α-GOS-enriched soy milk administered to Cb rats were 48 and 76 mM, respectively; 5, the concentrations of raffinose and stachyose in the α-GOS-enriched soy milk administered to HMA rats were 144 and 228 mM, respectively; 6, L. fermentum cultures were at 4 × 109 CFU/ml; 7, α-GOS-enriched soy milk (see 4) was added with a 2 % (v/v) inoculum of a 4 × 109 CFU/ml L. fermentum CRL722 suspension and was allowed to ferment for 16 h at 37°C.
