Fig. 1From: Phylogeny-structured carbohydrate metabolism across microbiomes collected from different units in wastewater treatment processPrincipal coordinate analysis (PCoA) plots depict Bray–Curtis distance between sludge samples using CAG content (a) and phylogeny distribution based on 16S rRNA genes (b) or based on CAG-encoding ORFs (c). Significance Bray–Curtis distance between groups is indicated by p value (analysis of similarity, ANOSIM). Eclipse is drawn with confidence limit of 0.68. Samples are, respectively, colored according to environmental categories of DO (anaerobic and aerobic), temperature (M mesophilic; A ambient temperature; T thermophilic) and salinity (saline and fresh) in the left, middle and right subfiguresBack to article page
