Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …

Despite the fact that heterotrophic nitrification was identified more than 100 years ago, the
biochemistry of heterotrophic nitrifiers is poorly known and their contribution to nitrification in …

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 third domain Archaea was known to thrive in extreme or anoxic environments based on
cultivation studies. Recent metagenomics-based approaches revealed a widespread …

Nitrification is a fundamental process in terrestrial nitrogen cycling. However, detailed
information on how climate change affects the structure of nitrifier communities is lacking …

Nitrification is a core process in the global nitrogen (N) cycle mediated by ammonia-
oxidizing microorganisms, including ammonia-oxidizing archaea (AOA) as a key player …

The ammonia monooxygenase (AMO) is a key enzyme in ammonia‐oxidizing archaea,
which are abundant and ubiquitous in soil environments. The AMO belongs to the copper …

Although the distribution of ammonia/nitrite oxidizers had been profiled in different habitats,
current understanding is still limited regarding their niche differentiation in the integrated …

Simple Summary Heavy nitrogen pollution is a major ecological problem for cold aquifers
near the zone of a radioactive waste surface repository. Unique microbial communities are …

Plastic marine debris is known to harbor a unique microbiome (termed the “plastisphere”)
that can be important in marine biogeochemical cycles. However, the temporal dynamics in …
