Short-term responses of the anammox process to Ni(II): nitrogen removal, mechanisms and inhibition recovery

Scientific Reports, 2022
Anaerobic ammonia oxidizing (anammox) has already been recognized as an innovative and economical nitrogen removal technology. However, the effect of heavy metals on anammox bacteria in aquatic ecosystem remains largely unknown.

Disturbance-based management of ecosystem services and disservices in partial nitritation-anammox biofilms [PDF]

, 2022
The resistance and resilience provided by functional redundancy, a common feature of microbial communities, is not always advantageous. An example is nitrite oxidation in partial nitritation-anammox (PNA) reactors designed for nitrogen removal in ...

Comparative Genome-Centric Analysis of Freshwater and Marine ANAMMOX Cultures Suggests Functional Redundancy in Nitrogen Removal Processes

Frontiers in Microbiology, 2020
There is a lack of understanding of the interaction between anammox bacteria and the flanking microbial communities in both freshwater (non-saline) and marine (saline) ecosystems.

Rapid cultivation of anammox sludge based on Ca-alginate cell beads

Water Science and Technology, 2022
Current gel entrapment technology has certain advantages for the enrichment of anammox sludge. In this study, the optimal preparation conditions and cultivation equipment of Ca-alginate cell beads for the culturing anammox sludge were proposed.

Effects of biotin on promoting anammox bacterial activity

Scientific Reports, 2021
Anaerobic ammonium oxidation (anammox) bacteria significantly improve the efficiency and reduce cost of nitrogen removal in wastewater treatment plants. However, their slow growth and vulnerable activity limit the application of anammox technology.

The influence of intense chemical pollution on the community composition, diversity and abundance of anammox bacteria in the Jiaojiang Estuary (China). [PDF]

PLoS ONE, 2012
Continuous chemical pollution is one of the most serious environmental problems in the Jiaojiang Estuary of the East Sea (China). This chemical pollution has significantly changed the estuarine environmental conditions and may have profoundly influenced ...

The application of 15N isotope tracer in differentiating denitrification, anammox and DNRA during anammox start-up by adding calcium nitrate

MethodsX, 2021
Denitrification, anaerobic ammonium oxidation (anammox) and dissimilatory reduction of nitrate to ammonium (DNRA) are important forms of nitrogen transformation process. The addition of calcium nitrate induces the coupling of denitrification, anammox and

An intracellular pH gradient in the anammox bacterium Kuenenia stuttgartiensis as evaluated by (31)P NMR [PDF]

, 2009
The cytoplasm of anaerobic ammonium oxidizing (anammox) bacteria consists of three compartments separated by membranes. It has been suggested that a proton motive force may be generated over the membrane of the innermost compartment, the “anammoxosome ...

Soil anammox and denitrification processes connected with N cycling genes co-supporting or contrasting under different water conditions

Environment International, 2020
The anaerobic ammonium oxidizing bacteria (anammox) are the hidden culprit behind the excessive nitrogen loss under a favorable environment, since their detection and abundance get disturbed by several unknown factors.
