Engineering Safety Through MOFs‐Based Nanocomposites: Advances in Design, Fabrication, and Deployment Across Emerging Domains

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Ensuring uncompromised safety across interconnected domains is vital for global societal sustainability. Metal–organic framework (MOF)‐based nanocomposites, owing to their intrinsically tunable structures and broad functional versatility, represent a powerful class of materials for safety‐related engineering.

Effect of Salt on the Metabolism of ‘Candidatus Accumulibacter’ Clade I and II

Frontiers in Microbiology, 2018
Saline wastewater is known to affect the performance of phosphate-accumulating organisms (PAOs) in enhanced biological phosphorus removal (EBPR) process. However, studies comparing the effect of salinity on different PAO clades are lacking. In this study,

Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

Ecological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

Low Acetate Concentrations Favor Polyphosphate-Accumulating Organisms over Glycogen-Accumulating Organisms in Enhanced Biological Phosphorus Removal from Wastewater

, 2016
Glycogen-accumulating organisms (GAOs) are thought to compete with polyphosphate-accumulating organisms (PAOs) in enhanced biological phosphorus removal (EBPR) wastewater treatment systems. A laboratory sequencing batch reactor (SBR) was operated for one

Complete Nutrient Removal Coupled to Nitrous Oxide Production as a Bioenergy Source by Denitrifying Polyphosphate-Accumulating Organisms.

Environmental Science and Technology, 2017
Coupled aerobic-anoxic nitrous decomposition operation (CANDO) is a promising emerging bioprocess for wastewater treatment that enables direct energy recovery from nitrogen (N) in three steps: (1) ammonium oxidation to nitrite; (2) denitrification of ...

The source of reducing power in the anaerobic metabolism of polyphosphate accumulating organisms (PAOs) – a mini-review

Water Science and Technology, 2010
Glycolysis has been generally accepted to be the source of reducing power used for the synthesis of polyhydroxyalkanoates (PHAs) in the anaerobic metabolism of polyphosphate accumulating organisms (PAOs). However, the tricarboxylic acid cycle (TCA) has also been suggested to contribute to the generation of reducing equivalents, creating some ...

Effect of pH reduction on polyphosphate- and glycogen-accumulating organisms in enhanced biological phosphorus removal processes

, 2010
We investigated the effect of pH reduction on polyphosphate-accumulating organisms (PAOs) and glycogen-accumulating organisms (GAOs) in the enhanced biological phosphorus removal (EBPR) process. Three laboratory-scale EBPR reactors were used.

Modelling the metabolism of the polyphosphate-accumulating organism Candidatus Accumulibacter.

Wastewater resulting from human activities must be treated to minimize the impact on the receiving ecosystems. One of such potential impacts in lakes and other water bodies is eutrophication, an excessive increase in their nitrogen and phosphorus content.

Discovering Polyphosphate and Polyhydroxyalkanoate-Accumulating Organisms Across Ecosystems: Phenotype-targeted Genotyping via FACS-sequencing

bioRxiv
Intracellular biopolymers serve versatile functions that allow microbes to adapt to fluctuating environmental conditions. The metabolic interdependence of dual intracellular polymers, namely polyphosphate (polyP) and polyhydroxyalkanoates (PHA), is a ...
