Shift in carbohydrate active enzyme and in vitro assessment of xylan utilization by representative B. pseudocatenulatum. A An ordinate analysis of CAZ profile. B The most differential carbohydrate active enzyme identified by DEseq2. C Growth curve (mean OD₆₀₀) of B. pseudocatenulatum DSM 20438 in MRS medium containing either 2% of the indicated carbon source or no carbohydrate (control). D xylanase activity of B. pseudocatenulatum DSM 20438 in MRS medium containing 2% of the indicated carbon source. E Acetate concentration of B. pseudocatenulatum DSM 20438 in MRS medium containing 2% of the indicated carbon source. FF dietary fiber deprivation, FF + xylan dietary fiber deprivation + xylan. C cecum, PC proximal colon, MC middle colon, DC distal colon, F feces, XOS xyl-oligosaccharides. Statistical analyses were done using one-way ANOVA. ^*P < 0.05
