Levels of Bifidobacteriaceae (log₁₀ (copies/mL)) (A), acetate (mM) (B), propionate (mM) (C), butyrate (mM) (D), acidity (pH) (E) and gas production (kPa) (F) at 24 h and 48 h upon inoculation with a fecal inoculum, as averaged across donors A, B, and C (test 1). Significant differences between any of the treatments and the untreated blank are indicated by an asteriks (p < 0.05; n = 3). 2′FL = 2′-O-fucosyllactose, LNnT = lacto-N-neotetraose, MIX = 4:1 mixture of 2′FL/LNnT.
