Phosphorus Removal from Aerobic Granular Sludge: Proliferation of Polyphosphate-Accumulating Organisms (PAOs) under Different Feeding Strategies

Processes, 2022
Aerobic granular sludge (AGS) is known for high phosphorus removal from wastewaters, and phosphorus can be recovered from high phosphorus-containing waste sludge granules. This study aimed at determining the feeding strategy that provides the best performance in terms of the proliferation of polyphosphate-accumulating organisms (PAOs) and phosphorus ...

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.

Poly-P-forming characteristics found in poly-P-accumulating microorganisms (phosphate-accumulating organisms [PAOs]) isolated from shrimp ponds in Vietnam

Fisheries and Aquatic Sciences
Significant amounts of phosphate (PO43–) in extensive shrimp ponds make an ideal survey for studying the PO43–-accumulating properties of phosphate-accumulating organisms (PAOs) and harvesting polyphosphate (poly-P). In this study, we evaluated the PO43–-

Trade‐offs between the instantaneous growth rate and long‐term fitness: Consequences for microbial physiology and predictive computational models

BioEssays, Volume 45, Issue 10, October 2023., 2023
We reflect on the use and limitations of current computational models of microbial growth. While models based on constraint‐based optimization are remarkably predictive for common model organisms, such as E. coli and S. cerevisiae, the trade‐offs that shape the adaptations in natural environments are still poorly understood.

Phosphorus recovery from hydrothermal carbonization of organic waste: a review

Journal of Chemical Technology &Biotechnology, Volume 98, Issue 10, Page 2365-2377, October 2023., 2023
Abstract Background This review sheds light on the topic of phosphorus (P) recovery from hydrothermal carbonization (HTC) of organic waste. The paper focuses on the rising need for securing alternative P sources for the increasing demand, in addition to the development of HTC as a thermochemical technique for waste valorization.

Diagnosing and characterizing the mechanisms of biological phosphorus removal at the Great Lakes Water Authority (GLWA) water resource recovery facility (WRRF)

Water Environment Research, Volume 95, Issue 7, July 2023., 2023
The growth of polyphosphate accumulating organisms (PAOs) requires volatile fatty acids (VFAs) that are generated in the sludge blanket of the secondary clarifiers, offering a greater quantity of anaerobic biomass than the anaerobic zones in the bioreactor. Additionally, there are possibilities for enhancing the effectiveness of bio‐P in current system.
