Principal coordinate analysis (PCA) ordination diagrams for AOB communities associated with the water quality parameters. The figure presents species and water quality correlations. Water quality parameters are indicated as arrows and the microbial communities indicated as (o). The first canonical axes for the microbial communities explained 70.5, 96.4, 98.8 and 99.7% of the variations for the: control (Ctrl, LsB, PsB and EsB) treatment tanks respectively
