Effects of oxygen on anoxic biodegradation of benzoate during continuous culture
|
ABSTRACT: In this study, various amounts of oxygen were added to denitrifying chemostats receiving benzoate to mimic the input of oxygen to anoxic zones of biological nutrient removal systems. The effect of oxygen on the biodegradative capability of the mixed-microbial culture for benzoate was investigated. The anoxic benzoate biodegradative capability of the culture was not significantly changed as the mass flowrate of oxygen was increased to 40% of the input benzoate chemical oxygen demand ...

The Effect of Residual Chemical Oxygen Demand on Anoxic and Aerobic Phosphate Uptake and Release with Various Intracellular Polymer Levels
Water Environment Research
; ABSTRACT: This study investigated the anoxic and aerobic phosphate uptake and release reactions and the fraction of denitrifying phosphate-accumulating organisms (DPAOs) under various initial chemical oxygen demand (COD) and residual COD conditions. The results showed that DPAOs and non-DPAOs could
