(a) Rarefaction analysis of the sludge sample from the UASB reactor. Rarefaction is shown for OTUs that contain unique sequences and OTUs with differences that do not exceed 3%, 5% or 10%. OTUs with ≥97% pairwise sequence identity are assumed to form the same species and genus, respectively; Taxonomic classification of bacterial 16s rRNA gene reads retrieved from UASB reactor at phylum (b) and class (c) levels using RDP classifier with a confidence threshold of 97%; (d) Heatmap showing the relative abundance and phylogenetic relationships of different genera retrieved from the sludge of the UASB reactor. The color indicates the percentage of a genus in total sequences.
