For more than 100 years it was believed that bacteria were the only group responsible for
the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative …

Abstract Treatment of waters contaminated with sulfur containing compounds (S) resulting
from seawater intrusion, the use of seawater (eg seawater flushing, cooling) and industrial …

Abstract The Anammox and Sulfate Reduction Ammonium Oxidation processes were
compared in two granular sequencing batch reactors operated for 160 days under anammox …

A surface-promoted sulfate-reducing ammonium oxidation reaction was discovered to
spontaneously take place on common inorganic aerosol surfaces undergoing solvation …

Identification of microorganisms by conventional methods requires the isolation of pure
cultures followed by laborious characterization experiments. These procedures are therefore …

The Earth is experiencing excessive nitrogen (N) input to its various ecosystems due to
human activities. How to effectively and efficiently remove N from ecosystems has been, is …

Biological nitrogen removal (BNR) is essential for the treatment of nitrogen-containing
wastewater. However, the requirement for aeration and the addition of external carbon …

Anaerobic digesters have been responsible for the removal of large fraction of organic
