Nitrogen-loss and associated microbial communities in sediments from the Yangtze Estuary and adjacent sea

Frontiers in Marine Science, 2022
IntroductionDenitrification and anammox play the crucial role for N removal processes in coastal ecosystems, but the ecological distribution of denitrifying and anammox microorganisms and their N removal rates in the Yangtze Estuary and its adjacent sea ...

Biogeography of anaerobic ammonia-oxidizing (anammox) bacteria

Frontiers in Microbiology, 2014
Anaerobic ammonia-oxidizing (anammox) bacteria are able to oxidize ammonia and reduce nitrite to produce N2 gas. After being discovered in a wastewater treatment plant (WWTP), anammox bacteria were subsequently characterized in natural environments ...

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.

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.

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.

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 ...

Anaerobic Ammonium Oxidation in Acidic Red Soils

Frontiers in Microbiology, 2018
Anaerobic ammonium oxidation (anammox) has been proven to be an important nitrogen removal process in terrestrial ecosystems, particularly paddy soils. However, the contribution of anammox in acidic red soils to nitrogen loss has not been well-documented

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 ...

Effect of Nitric Oxide on Anammox Bacteria [PDF]

Applied and Environmental Microbiology, 2010
ABSTRACT The effects of nitrogen oxides on anammox bacteria are not well known. Therefore, anammox bacteria were exposed to 3,500 ppm nitric oxide (NO) in the gas phase. The anammox bacteria were not inhibited by the high NO concentration but rather used it to oxidize additional ammonium to dinitrogen gas under conditions relevant to ...
