Polyhydroxybutyrate Production from Municipal Wastewater Activated Sludge with Different Carbon Sources

Air, Soil and Water Research, 2015
In this study, a sequencing batch reactor was set up and operated for over three months to cultivate polyphosphate-accumulating organisms polyphosphate-accumulating organisms (PAOs) in the enriched activated sludge. Batch studies were then carried out to

Ecological risk assessment of glyphosate and its possible effect on bacterial community in surface sediments of a typical shallow Lake, northern China

Ecotoxicology and Environmental Safety, 2023
Glyphosate is a widely used herbicide worldwide and its prevalent presence in aquatic ecosystems poses a threat to living organisms. This study evaluated potential ecological risk of glyphosate to sediment-dwelling organisms and assessed the probable ...

Floc-forming properties of polyphosphate accumulating organisms in activated sludge

Water Science and Technology, 2006
The physico-chemical characteristics of polyphosphate-accumulating organisms (PAO) involved in enhanced biological phosphorus removal (EBPR) was investigated in order to find a novel method for phosphorus recovery. If the physico-chemical characteristics of PAO are different from those of other main floc components, it may be possible to enrich PAO in ...

Predicting microbial community compositions in wastewater treatment plants using artificial neural networks

Microbiome, 2023
Background Activated sludge (AS) of wastewater treatment plants (WWTPs) is one of the world’s largest artificial microbial ecosystems and the microbial community of the AS system is closely related to WWTPs' performance.

Ecophysiology of putative polyphosphate-accumulating organisms revealed by FISH-Raman

, 2022
Phosphate is a vital, but limited resource, so recycling is crucial to support the increasing demand. The enhanced biological phosphorus removal process in wastewater treatment plants can ensure recycling of phosphate from the wastewater by the use of ...

An innovative continuous flow BNR-IC process for nutrients removal and phosphorus recovery from synthetic and real domestic wastewater

Journal of Environmental Engineering and Landscape Management, 2016
An innovative continuous flow process linking biological nutrients removal (BNR) with induced crystallization (IC) was used to remove nutrients and recover phosphorus (P) from synthetic and real domestic wastewater.

Comparative Genomics of Members of the Genus Defluviicoccus With Insights Into Their Ecophysiological Importance

Frontiers in Microbiology, 2022
Members of the genus Defluviicoccus occur often at high abundances in activated sludge wastewater treatment plants designed to remove phosphorus, where biomass is subjected to alternating anaerobic feed/aerobic famine conditions, believed to favor the ...

Phenotypic prevalence index: Diversity of polyphosphate-accumulating organisms (PAOs) and insights in unknown PAOs revealed by combined fluorescence-activated cell sorting (FACS) and 16S rRNA gene sequencing.

Water Research
Despite the recognized crucial role of polyphosphate-accumulating organisms (PAOs) in Enhanced Biological Phosphorus Removal (EBPR) process for phosphorus removal and recovery in wastewater treatment, knowledge gaps remain in the diversity and elasticity

Metabolic modelling of anaerobic amino acid uptake and storage by fermentative polyphosphate accumulating organisms.

Water Research
Existing enhanced biological phosphorus removal (EBPR) models do not fully describe the metabolism of fermentative polyphosphate accumulating organisms (fPAOs), particularly under mixed substrate conditions representative of fermentation-enhanced EBPR (F-
