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 …

The oxidation of ammonia plays a significant role in the transformation of fixed nitrogen in
the global nitrogen cycle. Autotrophic ammonia oxidation is known in three groups of …

The abundance of different SSU rRNA (“16S”) gene sequences in environmental samples is
widely used in studies of microbial ecology as a measure of microbial community structure …

Ammonia-oxidizing microbial communities involved in ammonia oxidation under low
dissolved oxygen (DO) conditions (< 0.3 mg/L) were investigated using chemostat reactors …

In this study, we successfully demonstrated that 454 pyrosequencing was a powerful
approach for investigating the bacterial communities in the activated sludge, digestion …

This study intended to evaluate the combined effects of both biochar and organic fertilizer on
nitrous oxide (N 2 O) fluxes and composition of nitrifier and denitrifier of saline-alkali soil …

Soil nitrification is an important process for agricultural productivity and environmental
pollution. Though one cultivated representative of ammonia-oxidizing Archaea from soil has …

The role of ammonia-oxidizing archaea (AOA) in nitrogen cycling in marine sediments
remains poorly characterized. In this study, we enriched and characterized AOA from marine …

Nitrogen management measures (NMMs) such as the application of urease inhibitors (UIs),
synthetic nitrification inhibitors (SNIs), and biochar (BC) are commonly used in mitigating …

The ongoing climate change is predicted to induce more weather extremes such as frequent
drought and high‐intensity precipitation events, causing more severe drying‐rewetting …
