Characterisation of Phosphate Accumulating Organisms and Techniques for Polyphosphate Detection: A Review [PDF]
Sensors, 2016 Phosphate minerals have long been used for the production of phosphorus-based chemicals used in many economic sectors. However, these resources are not renewable and the natural phosphate stocks are decreasing.

Identification and comparison of aerobic and denitrifying polyphosphate‐accumulating organisms
Biotechnology and Bioengineering, 2003 AbstractTwo laboratory‐scale sequencing batch reactors (SBRs) were operated for enhanced biological phosphorus removal (EBPR) in alternating anaerobic–aerobic or alternating anaerobic–anoxic modes, respectively. Polyphosphate‐accumulating organisms (PAOs) were enriched in the anaerobic–aerobic SBR and denitrifying PAOs (DPAOs) were enriched in the ...

Multiple extracellular polymeric substance pathways transcribed by Accumulibacter and the flanking community during aerobic granule formation and after influent modification [PDF]
Applied and Environmental MicrobiologyAerobic granular sludge is a biological wastewater treatment process in which a microbial community forms a granular biofilm. The role of Candidatus Accumulibacter in the production of a biofilm matrix composed of extracellular polymeric substances was ...
