Additional file 1 of Impact of lignans in oilseed mix on gut microbiome composition and enterolignan production in younger healthy and premenopausal women: an in vitro pilot study

Additional file 1: Fig. S1. The biodiversity of the faecal-derived microbial communities from premenopausal and younger healthy women tends to decrease over time in 24-h fermentation experiments in the presence of oilseed mix and inulin. Boxplots showing the distribution of alpha diversity values, according to the number of observed amplicon sequence variants (ASVs, upper panel) and Faith’s Phylogenetic Diversity index (PD whole tree, lower panel), for the faecal microbial communities from premenopausal (PD) and younger healthy (YD) women at 0 (T0), 5 (T5) and 24 h (T24) of fermentation in the presence of oilseed mix (shades of green), inulin (as a positive control; shades of red) or without additions (negative control, “Ctr -”; shades of yellow).
