Summary of 16S rRNA gene sequencing data and α-diversity values (Chao1, Shannon index, and Simpson index) in faecal samples obtained from a human intervention study.
| Human intervention study (n = 4) | ||||
|---|---|---|---|---|
| washout-1 | αCD | washout-2 | DEX | |
| Read counts | 116,239 ± 38,393 | 129,196 ± 42,459 | 138,811 ± 48,413 | 125,079 ± 42,432 |
| Observed OTUs | 1,518 ± 288 | 1,548 ± 471 | 1,534 ± 460 | 1,620 ± 527 |
| Chao1 | 2,416 ± 558 | 2,459 ± 675 | 2,457 ± 538 | 2,530 ± 752 |
| Shannon index | 5.70 ± 0.36 | 5.35 ± 0.69 | 5.53 ± 0.70 | 5.64 ± 0.67 |
| Simpson index | 0.95 ± 0.01 | 0.92 ± 0.04 | 0.94 ± 0.03 | 0.95 ± 0.02 |
Four human volunteers participated in this study. Faecal samples were obtained after the subjects drank water for 14 days (washout-1 or washout-2) and ate α-cyclodextrin (αCD) or indigestible dextrin (DEX) for seven days.
The values show the mean ± standard deviation.
No statistical difference was detected between faecal samples (washout-1, αCD, washout-2, and DEX) in terms of observed operational taxonomic units (OTUs), Chao1, Shannon index, and Simpson index (Kruskal-Wallis test).
