Distributions of OTUs and NJ phylogenetic tree: (a) AOA amoA gene; (b) AOB 16S rRNA gene. Sequences retrieved in this study are shown in red and purple with “OTU” in the names. The ratios of amounts of sequences within each OTU to the total AOA or AOB sequences are displayed by the number in parentheses.
