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 continuous increase of the greenhouse gas nitrous oxide (N2O) in the atmosphere due
to increasing anthropogenic nitrogen input in agriculture has become a global concern. In …

Autotrophic archaeal and bacterial ammonia-oxidisers (AOA and AOB) drive soil nitrification.
Ammonia limitation, mixotrophy, and pH have been suggested as factors providing niche …

High and low rates of ammonium supply are believed to favour ammonia-oxidising bacteria
(AOB) and archaea (AOA), respectively. Although their contrasting affinities for ammonium …

Nitrogen fertilisation of agricultural soil contributes significantly to emissions of the potent
greenhouse gas nitrous oxide (N2O), which is generated during denitrification and, in oxic …

Electrophoresis, DGGE) 指纹图谱技术, 评价两种技术研究土壤微生物群落结构的优缺点.[方法] …

Archaea, primarily Crenarchaeota, are common in soil; however, the structure of soil
archaeal communities and the factors regulating their diversity and abundance remain …

The recent discovery of complete ammonia oxidizers (comammox Nitrospira) challenged the
paradigm of the two-step nitrification mediated by two distinct groups of nitrifiers, and raised …

Genes of archaea encoding homologues of ammonia monooxygenases have been found
on a widespread basis and in large amounts in almost all terrestrial and marine …

Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in
the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing …
