1Data are expressed as least-square mean ± SEM for each treatment group.
2Only genera with at least one mean with >1.0% relative abundance were considered for interpretation. Bacterial genera names preceded by (F) indicates that genera are associated with a specific taxonomic family and has not yet been further classified.
a,bMeans without a common superscript letter differ (P < 0.05).
