Effect of Ethanol and Glycerol on the diversity of polyphosphate and glycogen accumulating organisms in enhanced biological phosphorus removal systems

To investigate the impact of glycerol and ethanol dosing on the performance of the Enhanced Biological Phosphorus Removal (EBPR) process and the diversity of polyphosphate (PAOs) and glycogen accumulating organisms (GAOs), a series of studies with multiple adaptation phases was conducted using an automated sequencing batch reactor system. Overall, phosphorus release driven by glycerol and ethanol is significantly limited. Whole native DNA sequencing emphazises the underestimated role of Dechloromonas and Tessaracoccus in EBPR.
