Figure 2. DESS preserves microbial mock community structure better than PBS or glycerol.

(A) Relative abundances of genera in mock community samples. (B) PCoA of Weighted UniFrac distances between mock communities stored in DESS, PBS, or glycerol, indicated by different colors, for 0, 1, or 2 months, indicated by different shapes. (C) Heatmap showing log2 fold changes in relative abundance of genera in the mock community compared to t₀ samples. *Indicate where these changes were significantly different between preservatives (Bonferroni corrected p-values: *p < 0.01, ***p < 0.001).
