Bar charts comparing species diversity (A) and richness (B) between the different groups (GSM, DTA81, LGG, and GNI) before (t0) and after (t1) the experimental period. Values are means ± SEM (n = 4). **, p ≤ 0.01. Principal coordinate analysis (PCoA) based on weighted (C) and unweighted (D) UniFrac distances for GSM, DTA81, LGG, and GNI in the time-points t0 and t1. Permutational multivariate analysis of variance (PERMANOVA) was carried out to detect significant dissimilarities among the different experimental groups.
