Critical Review of Polyphosphate and Polyphosphate Accumulating Organisms for Agricultural Water Quality Management

, 2021
Despite ongoing management efforts, phosphorus (P) loading from agricultural landscapes continues to impair water quality. Wastewater treatment research has enhanced our knowledge of microbial mechanisms influencing P cycling, especially regarding ...

Revealing taxon-specific heavy metal-resistance mechanisms in denitrifying phosphorus removal sludge using genome-centric metaproteomics

Microbiome, 2021
Background Denitrifying phosphorus removal sludge (DPRS) is widely adopted for nitrogen and phosphorus removal in wastewater treatment but faces threats from heavy metals.

Modeling the aerobic metabolism of polyphosphate-accumulating organisms enriched with propionate as a carbon source

, 2007
In enhanced biological phosphorus removal (EBPR) systems, polyphosphate-accumulating organisms (PAOs) are primarily responsible for removing phosphate from wastewater.

“Candidatus Dechloromonas phosphoritropha” and “Ca. D. phosphorivorans”, novel polyphosphate accumulating organisms abundant in wastewater treatment systems [PDF]

, 2021
Members of the genus Dechloromonas are often abundant in enhanced biological phosphorus removal (EBPR) systems and are recognized putative polyphosphate accumulating organisms (PAOs), but their role in phosphate removal is still unclear.

Recovering Critical Elements From Wastewater for Battery Materials: A Review

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

Mapping of Several Putative Polyphosphate-Accumulating Organisms [PDF]

, 2021
Phosphate (P) is a vital resource, but it is limited in its natural occurrence so recycling will become important to support the increasing demand. By using the Enhanced Biological Phosphorus Removal (EBPR) process in wastewater treatment plants (WWTPs),

Comparing off‐flavor trends in freshwater recirculating aquaculture systems with microbially mature or immature biofilters while growing Atlantic salmon Salmo salar

Journal of the World Aquaculture Society, Volume 56, Issue 6, December 2025.
Abstract Geosmin (GSM) and 2‐methylisoborneol (MIB) cause objectionable off‐flavors in fish produced in recirculating aquaculture systems (RAS). Remediation solutions have not been developed; therefore, a study was conducted to determine if microbial maturity limits off‐flavor production. Triplicate RAS with newly established nitrification (“immature”)
