Effect of whey products on in vitro expansion of bacterial genera derived from healthy infants. The relative abundance of selected bacterial genera before (A) and after (B–D) in vitro incubations supplemented with extensively (eHW), partially hydrolysed (pHW-22.4% or pHW-7.2%) or intact (iW) whey products. The results after in vitro incubations (B–D) are normalised to the median of the iW group. Each bar represents one donor/culture (A), each symbol represents an in vitro incubation replicate, which is the average of three technical qPCR replicates and horizontal lines indicate median values (B–D). The symbol shape indicates the inoculum source. Statistically significant differences between groups are indicated as *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001.
