Eight human faeces samples (FEC), corresponding cultures (CUL), and corresponding cultures treated with 0.2% indigestible dextrin (DEX), α-cyclodextrin (αCD), or dextran (DXR) were sampled at 30 h of fermentation.
The values show the mean ± standard deviation.
Statistical differences between samples were evaluated with respect to observed operational taxonomic units (OTUs), Chao1 estimator, Shannon index, and Simpson index.
Asterisks (*) indicate significant differences between faeces from eight healthy subjects and corresponding cultures without or with prebiotics (*P < 0.05 and **P < 0.01, Kruskal-Wallis test).
Pounds (#) indicate significant differences between cultures with and without prebiotics (# P < 0.05 and ## P < 0.01, Kruskal-Wallis test).
