^aData are shown as means ± standard error of the mean (C group, n=8; KB group, n=5; others, n=6).

Tukey–Kramer HSD test was conducted as a statistical analysis. Different superscript letters represented significant differences among groups at p<0.05.

C: control-diet-fed, B. longum administered; KB: 1-kestose-fed, B. longum administered; KP: 1-kestose-fed, 1×PBS administered; RB: raffinose-fed, B. longum administered; RP: raffinose-fed, 1×PBS administered; PD: phylogenetic diversity.
