Table 1.

Differentially abundant taxa at family level among four gut sites (ascending colon, descending colon, rectum, and stool) in the live LM.

Family	Relative abundance (%)	Padj	Gut sites compared	log2FC
Lachnospiraceae	15.8	0.0012	Rectum vs Stool	0.3
			Descending colon vs Stool	0.7
			Ascending colon vs Stool	1.0
Veillonellaceae	2.1	0.011	Rectum vs Stool	2.5
			Descending colon vs Stool	2.2
			Ascending colon vs Stool	2.3

The live LM samples (n = 40; ten subjects over four gut sites) were used in DESeq2 analysis with full model of ~ subject + gut_sites and reduced model of ~ subject.

Criteria for inclusion: Relative abundance > 1% and padj < 0.01.

Relative abundance: mean on relative abundance of normalized counts for subset samples.

padj: the Benjamini–Hochberg adjusted P value.

log2FC: log2(fold change).

Gut sites compared: e.g., “Rectum vs Stool” means that log2FC means log2(Rectum/Stool).

LM luminal microbiota.
