“…It was reported in the previous studies that these bacteria can be used in the biological P treatment and showed the high P removal efficiencies under the best optimal conditions (Kim et al, 2010;Yoo et al, 2011;Kim et al, 2012).…”

This study was initiated to quantitatively evaluate the effects of five heavy metals (Cd, Cu, Zn, Pb, and Ni) on growth and P removal efficiencies of Pseudomonas taeanensis, known as the phosphorus accumulating microorganism. The heavy metals were added individually and with the binary mixture to the batch culturing system of Pseudomonas taeanensis. IC 50 and EC 50 were used to quantitatively evaluate their effects on the growth and phosphorus removal efficiency of Pseudomonas taeanensis in those treatments. Additionally, additive index value method was used to evaluate the interactive effects of heavy metals for Pseudomonas taeanensis in this study. As those heavy metals were singly added to Pseudomonas taeanensis, the greatest inhibitory effect on its growth and P removal efficiency was observed in Cd, whereas, the smallest effect was found in Ni. As the concentrations of all heavy metals added were gradually increased, its growth and P removal efficiency was correspondingly decreased. Specifically, IC 50 of Pseudomonas taeanensis for Cd, Cu, Zn, Pb, and Ni were 0.44 mg L -1 , 5.12 mg L -1 , 7.46 mg L -1 , 8.37 mg L -1 and 14.56 mg L -1 , respectively. The P removal efficiency of Pseudomonas taeanensis was 81.1%. EC 50 values of Pseudomonas taeanensis for Cd, Cu, Zn, Pb, and Ni were 0.44 mg L -1 , 4.08 mg L -1 , 7.17 mg L -1 , 8.90 mg L -1 and 11.26 mg L -1 , respectively. In the binary treatments of heavy metals, the lowest IC 50 and EC 50 were found in the Cd + Cu treatment, whereas, the highest IC 50 and EC 50 were found in the Zn + Pb and Pb + Ni treatments, respectively. Most of the interactive effects for the binary mixture treatments of heavy metals were antagonistic. Based on the results obtained from this study, it appears that they could provide the basic information about the toxic effects of the respective individual and binary treatments of heavy metals on the growth and P removal efficiency of other phosphorus accumulating organisms.

“…According to the previous studies, PAOs are sensitive to many factors including fluctuation of substrate concentration, inhibition from NO2 - (Saito et al, 2004), FNA (Zhou et al, 2010), metal ions (Kim et al, 2010, Tsai et al, 2016, dissolved oxygen, pH and temperature change (Lopez-Vazquez et al, 2009). Besides these, a well-known competitor of PAO, GAO, which also consumed carbon as PAO but does not contribute to phosphorous removal is blamed primarily for the deterioration of EBPR process (Gebremariam et al, 2011).…”
