Anammox bacteria adapt to long-term light irradiation in photogranules.

Water Research, 2023
Photogranules composed of algae, nitrifiers, and anammox bacteria are promising for nitrogen removal from wastewater with reduced aeration and carbon emissions.

Electron transfer mechanism of intracellular carbon-dependent DNRA inside anammox bacteria.

Water Research, 2023
Generally, anaerobic ammonium oxidation (anammox) converts nitrite (NO2-) and ammonium (NH4+) to nitrogen gas (N2) but generates some nitrate (NO3-) (equivalent to 11% of inlet total nitrogen (TN)).

Anammox bacteria in treating ammonium rich wastewater: Recent perspective and appraisal.

Bioresource Technology, 2021
The discovery of anammox process has provided eco-friendly and low-cost means of treating ammonia rich wastewater with remarkable efficiency. Furthermore, recent studies have shown that the possibility of operating the anammox process under low ...

Biochar-mediated DNRA pathway of anammox bacteria under varying COD/N ratios.

Water Research, 2022
Coupling dissimilatory nitrate reduction to ammonium (DNRA) pathway with anammox process has a prominent advantage in enhancement of nitrogen removal. However, the anammox bacteria driven-DNRA is difficult to proceed at normal autotrophic circumstance ...

Anammox bacteria: from discovery to application

Nature Reviews Microbiology, 2008
Anaerobic ammonium oxidation (anammox) bacteria, which were discovered in waste-water sludge in the early 1990s, have the unique metabolic ability to combine ammonium and nitrite or nitrate to form nitrogen gas. This discovery led to the realization that a substantial part of the enormous nitrogen losses that are observed in the marine environment--up ...

Activities and metabolic versatility of distinct anammox bacteria in a full-scale wastewater treatment system.

Water Research, 2021
Anaerobic ammonium oxidation (anammox) is a key N2-producing process in the global nitrogen cycle. Major progress in understanding the core mechanism of anammox bacteria has been made, but our knowledge of the survival strategies of anammox bacteria in ...

Comammox Nitrospira cooperate with anammox bacteria in a partial nitritation-anammox membrane bioreactor treating low-strength ammonium wastewater at high loadings.

Water Research
Research has revealed that comammox Nitrospira and anammox bacteria engage in dynamic interactions in partial nitritation-anammox reactors, where they compete for ammonium and nitrite or comammox Nitrospria supply nitrite to anammox bacteria.

Maximum specific growth rate of anammox bacteria revisited

Water Research, 2017
Anammox bacteria have long been considered to be slow-growing bacteria. However, it has recently been reported that they could grow much faster than previously thought when they were cultivated in a membrane bioreactor (MBR) with a step-wise decrease in the solid retention time (SRT).

From freshwater anammox bacteria (FAB) to marine anammox bacteria (MAB): A stepwise salinity acclimation process

Science of The Total Environment, 2021
An investigation into the effect of stepwise saline introduction (3-20 g·L-1 NaCl) on the anaerobic ammonium oxidation (anammox) process in a lab-scale sequencing batch reactor was carried out for 252 days by evaluating the changes in influent and effluent nitrogen concentrations, conductivity, microbial extracellular polymeric substances' (EPS) ionic ...

Spatiotemporal Assembly and Immigration of Heterotrophic and Anammox Bacteria Allow a Robust Synergy for High-Rate Nitrogen Removal.

Environmental Science and Technology, 2023
The novel partial denitrification-driven anammox (PD/A) is an energy-efficient method for nitrogen removal from wastewater. However, its stability and efficiency are impeded by the competition between heterotrophic denitrifying bacteria and relatively ...
