Fig. 3From: What could the entire cornstover contribute to the enhancement of waste activated sludge acidification? Performance assessment and microbial community analysisOTU networks of the bacterial communities (a). Overlaps of the bacterial communities based on OTU (3% distance). The shared OTUs were analyzed at phylum level (b). Relative abundance was defined as the number of sequences per sample. Taxonomic classification of pyrosequences from the four WAS bacterial communities at the phylum (c), class (d) and genus (e) levelsBack to article page
