Widespread detection of Candidatus Accumulibacter phosphatis, a polyphosphate‐accumulating organism, in sediments of the Columbia River estuary

Environmental Microbiology, 2019
Enhanced biological phosphorus removal (EBPR) exploits the metabolism of polyphosphate-accumulating organisms (PAOs) to remove excess phosphorus (P) from wastewater treatment. Candidatus Accumulibacter phosphatis (Accumulibacter) is the most abundant and

Sulphide effects on the physiology of Candidatus Accumulibacter phosphatis type I

Applied Microbiology and Biotechnology, 2017
Sulphate-rich wastewaters can be generated due to (i) use of saline water as secondary-quality water for sanitation in urban environments (e.g. toilet flushing), (ii) discharge of industrial effluents, (iii) sea and brackish water infiltration into the sewage and (iv) use of chemicals, which contain sulphate, in drinking water production.

Potential for Growth of Candidatus 'Accumulibacter phosphatis' in an Aerobic Shaking Culture

Journal of Water and Environment Technology, 2010
Candidatus 'Accumulibacter phosphatis' ('Accumulibacter') is known as polyphosphate-accumulating organism found in the enhanced biological phosphorus removal (EBPR) activated sludge processes. 'Accumulibacter' is a yet-to-be isolated bacteria, and the growth of 'Accumulibacter' under aerobic conditions is still unknown. In this study, the potential for

Denitrification of nitrate and nitrite by ‘Candidatus Accumulibacter phosphatis’ clade IC

Water Research, 2016
Phosphate accumulating organisms (PAO) are assumed to use nitrate as external electron acceptor, allowing an efficient integration of simultaneous nitrogen and phosphate removal with minimal organic carbon (COD) requirements. However, contradicting findings appear in literature regarding the denitrification capacities of PAO due to the lack of clade ...

Enrichment and characterization of a psychrophilic ‘Candidatus Accumulibacter phosphatis’ culture

International Biodeterioration & Biodegradation, 2017
Abstract Enhanced Biological phosphorous removal (EBPR) processes, often operated at low temperatures, are utilised world-wide, but currently little is known regarding enrichment cultures and the characteristics of active organisms (“Candidatus Accumulibacter phosphatis” (Accumulibacter)) under psychrophilic conditions.
