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

Innovation in decarbonizing wastewater treatment is urgent in response to global climate
change. The practical implementation of anaerobic ammonium oxidation (anammox) …

This study developed a new process that stably produced ammonium nitrate (NH 4 NO 3),
an important and commonly used fertilizer, from the source-separated urine by comammox …

Agricultural practices such as extensive manure application (containing residual antibiotics)
as fertilizer can also contribute to antibiotic pollution in soil, besides nitrous oxide (N2O) …

The recent discovery of Nitrospira species capable of complete ammonia oxidation
(comammox) in non-marine natural and engineered ecosystems under mesothermal …

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 …

Nitrification is highly crucial for both anammox systems and the global nitrogen cycle. The
discovery of complete ammonia oxidation (comammox) challenges the inherent concept of …

As a newly discovered group of ammonia-oxidizing microorganisms, complete ammonia
oxidizing (comammox) Nitrospira has been widely found in various oligotrophic ecosystems …

The recent discovery of complete ammonia oxidation (comammox) has increased our
understanding of nitrification. Although comammox has been shown to play an important …

Antibiotics have become emerging pollutants occurring in wastewater, influencing the
activity of microorganisms responsible for wastewater treatment. Moreover, the potential …
