Polyphosphate accumulating organisms (PAOs) are essential for phosphorus removal in wastewater treatment plants (WWTPs); however, their global distribution patterns and potential ecological functions across diverse activated sludge systems remain poorly understood. Here, we analyzed 226 activated sludge metagenomes from 142 WWTPs across six continents,

Metabolic Shift of Polyphosphate-Accumulating Organisms With Different Levels of Polyphosphate Storage [PDF]
Water Research, 2012 Previous studies have shown that polyphosphate-accumulating organisms (PAOs) are able to behave as glycogen-accumulating organisms (GAOs) under different conditions.

Biofilm sequencing batch reactor (BSBR) can achieve efficient phosphate (P) removal and enrichment, but its process performance and metabolic mechanisms for P removal and enrichment of municipal wastewater remain largely unclear. In the present study, we assessed the P removal and enrichment of municipal wastewater at influent P concentrations of 2.5 ...

Freshwater Science, 2017
AbstractP availability often limits primary production in freshwater ecosystems and excessive P inputs promote accelerated eutrophication. Microbial mechanisms may control O2-dependent uptake/release of P in stream sediments and biofilms, but specific organisms responsible for these cycles have not been identified. Polyphosphate accumulating organisms (
