Net-zero emission and self-sustaining carbon-neutral have been widely encouraged and
intensively explored in wastewater treatment, as the wastewater industry accounts for …

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

The nitrogen cycle plays a major role in aquatic nitrogen transformations, including in the
terrestrial subsurface. However, the variety of transformations remains understudied. To …

Nitrification, the oxidation of ammonia to nitrate, is an essential process in the
biogeochemical nitrogen cycle. The first step of nitrification, ammonia oxidation, is performed …

The recent discovery of comammox (complete ammonia oxidation) Nitrospira has upended
the long-held nitrification paradigm. Although comammox Nitrospira have been identified in …

The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a
breakthrough in the history of nitrification research. Nitrospira inopinata, which was obtained …

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

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 …

Anaerobic ammonium oxidation (anammox) is a key N 2-producing process in the global
nitrogen cycle. Major progress in understanding the core mechanism of anammox bacteria …

In this study, the metal (loid) fractions in two alkaline iron tailings areas with similar physico-
chemical properties and the enrichment ability of dominant plants in these areas were …
