Microbial nitrite oxidation is the primary pathway that generates nitrate in wastewater
treatment systems and can be performed by a variety of microbes: namely, nitrite-oxidizing …

Nitrification is a key process of the biogeochemical nitrogen cycle and of biological
wastewater treatment. The second step, nitrite oxidation to nitrate, is catalyzed by …

Nitrite oxidation is the primary pathway that generates nitrate in engineered systems.
However, little is known about the role of a novel nitrite-oxidizing bacteria (NOB) genus …

Nitrification has an immense impact on nitrogen cycling in natural ecosystems and in
wastewater treatment plants. Mathematical models function as tools to capture the …

Numerous past studies have shown members of the genus Nitrospira to be the predominant
nitrite-oxidizing bacteria (NOB) in nitrifying wastewater treatment plants (WWTPs). Only …

Nitrification activities and microbial populations of ammonium oxidizing bacteria (AOB) and
nitrite oxidizing bacteria (NOB) were investigated in 10 full-scale biological nutrient removal …

Oxidation of ammonium to nitrite rather than nitrate, ie, nitritation, is critical for autotrophic
nitrogen removal. This study demonstrates a robust nitritation process in treating low …

Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, nitrite oxidation to
nitrate, which is an important process of the biogeochemical nitrogen cycle. NOB were …

Genus Nitrospira and Nitrobacter species are the key nitrite-oxidizing bacteria (NOB) in
nitrifying wastewater treatment plants. It has been hypothesized that genus Nitrospira are K …

Nitrification is an essential process for N removal in activated sludge to avoid toxicity of
ammonium and nitrite. Besides Nitrospira,“Candidatus Nitrotoga” has been identified as a …
