Organic acid profiles in fecal samples. A Succinic, lactic, acetic, propionic, butyric, and total organic acid levels of fecal samples expressed in μmol/g feces (wet weight). Asterisks (*) indicate significance after a two-sided Mann-Whitney t test. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. Samples derived from experiment 1 and experiment 2 (Fig. 1F) are colored orange and green, respectively. B Partial redundancy analysis (pRDA) of microbiota at genus level with diet groups as explanatory variables with Hca (yellow squares), HcaGOS (blue squares), HcaInu (red squares), Lca (yellow circles), LcaGOS (blue circles), and LcaInu (red circles) and volatile acid profiles as supplementary variables with succinic acid (SA), lactic acid (LA), acetic acid (AA), propionic acid (PA), and butyric acid (BA). Partial redundancy analysis (pRDA) of microbiota at genus level with organic fecal acid concentrations as explanatory variable (corrected for experiment) showing the 10 most explanatory genera on the x-axis with C lactic acid (LA), D acetic acid (AA), and E propionic acid (PA). Sample labels for experiment 1 and experiment 2 (Fig. 1F) contain an asterisk (*) or are empty, respectively
