In the Anthropocene, nitrogen pollution is becoming an increasing challenge for both
mankind and the Earth system. Microbial nitrogen cycling begins with aerobic nitrification …

Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered
water treatment systems. The sequential steps of this respiratory process are carried out by …

The recent discovery of complete ammonia oxidation (comammox) bacteria has
fundamentally upended the traditional two-step nitrification conception, but their functional …

The recent discovery of complete ammonia oxidation (comammox) process in a single
organism challenged the division of labor between two functional groups in the classical two …

As drinking water travels from its source, through various treatment processes, hundreds to
thousands of kilometres of distribution network pipes, to the taps in private homes and public …

Elevated concentrations of ammonium and methane in groundwater are often associated
with microbiological, chemical and sanitary problems during drinking water production and …

Nitrification is an intermediary reaction common to various processes applied to treat
nitrogen-containing wastewaters. The genus Nitrospira is the most diverse among nitrifying …

The membrane fouling triggered by biofouling layer is the critical factor limiting the
application of biofiltration-facilitated gravity-driven membrane (GDM) system in …

Complete ammonia oxidizers (comammox) are a group of ubiquitous chemolithoautotrophic
bacteria capable of deriving energy from the oxidation of ammonia to nitrate via nitrite. Here …

Nitrogen removal is a critical process in water treatment plants (WTPs) and wastewater
treatment plants (WWTPs). The recent discovery of a novel bacterial process, complete …
