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 …

Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

The field of microbiome research has evolved rapidly over the past few decades and has
become a topic of great scientific and public interest. As a result of this rapid growth in …

Nitrogen is an essential component of all living organisms and the main nutrient limiting life
on our planet. By far, the largest inventory of freely accessible nitrogen is atmospheric …

Nitrification, the oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−), is a key
process of the biogeochemical nitrogen cycle. For decades, ammonia and nitrite oxidation …

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 …

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 …

Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …

Nitrification, the oxidation of ammonia via nitrite to nitrate, has been considered to be a
stepwise process mediated by two distinct functional groups of microorganisms. The …

The novel biological nitrogen removal process has been extensively studied for its high
nitrogen removal efficiency, energy efficiency, and greenness. A successful novel biological …
