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, as a crucial step in nitrogen cycling and plant nutrition, is a biologically
mediated process responsible for enormous losses of nitrogen fertilizer and a contributor to …

Microbial communities play important roles in all ecosystems and yet a comprehensive
understanding of the ecological processes governing the assembly of these communities is …

Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to be
a two-step process catalysed by chemolithoautotrophic microorganisms oxidizing either …

Nitrogen (N) pollution has emerged as one of the major threat to global sustainable
development and has received increasing attention. Manganese (Mn) is the third most …

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 …

It is now clear that several of the filamentous bacteria in activated sludge wastewater
treatment plants globally, are members of the phylum Chloroflexi. They appear to be more …

Nitrogen (N) is widely distributed in the lithosphere, hydrosphere, atmosphere and
biosphere. It is a basic component of every plant cell as well as microorganisms, as a …

The recent discovery of bacteria within the genus Nitrospira capable of complete ammonia
oxidation (comammox) demonstrated that the sequential oxidation of ammonia to nitrate via …

Nitrospira are a diverse group of nitrite-oxidizing bacteria and among the environmentally
most widespread nitrifiers. However, they remain scarcely studied and mostly uncultured …
