Increased replication of dissimilatory nitrate-reducing bacteria leads to decreased anammox bioreactor performance

open access: yesMicrobiome, 2020
Background Anaerobic ammonium oxidation (anammox) is a biological process employed to remove reactive nitrogen from wastewater. While a substantial body of literature describes the performance of anammox bioreactors under various operational conditions ...

Biochemistry and molecular biology of anammox bacteria

open access: yesCritical Reviews in Biochemistry and Molecular Biology, 2009
Anaerobic ammonium-oxidizing (anammox) bacteria are one of the latest additions to the biogeochemical nitrogen cycle. These bacteria derive their energy for growth from the conversion of ammonium and nitrite into dinitrogen gas in the complete absence of oxygen.

Increased salinity improves the thermotolerance of mesophilic nitrification [PDF]

open access: yes, 2014
Nitrification is a well-studied and established process to treat ammonia in wastewater. Although thermophilic nitrification could avoid cooling costs for the treatment of warm wastewaters, applications above 40 A degrees C remain a significant challenge.
