Principal component analysis (PCA) based on luminal (A) or mucosal (B) microbial composition in the proximal and distal colon of the quad-M-SHIME at the end of the control (C: Day 14) and treatment period (TR: Day 35). The PCA is based on data of the 10 most abundant families as detected via 16S-targeted Illumina sequencing across all samples. Arrows indicate the chronological evolution of samples along the experiment. cRG-I = carrot-derived Rhamnogalacturonan I, DC = distal colon, PC = proximal colon.
