Ammonia oxidation is a fundamental core process in the global biogeochemical nitrogen
cycle. Oxidation of ammonia (NH3) to nitrite (NO2−) is the first and rate-limiting step in …

Archaea are a domain of prokaryotic organisms with intriguing physiological characteristics
and ecological importance. In Microbial Biotechnology, archaea are historically …

The accrual of genomic data from both cultured and uncultured microorganisms provides
new opportunities to develop systematic taxonomies based on evolutionary relationships …

Ammonia-oxidizing microorganisms (AOM) contribute to one of the largest nitrogen fluxes in
the global nitrogen budget. Four distinct lineages of AOM: ammonia-oxidizing archaea …

Nitrification, the oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−), is a key
process of the biogeochemical nitrogen cycle. For decades, ammonia and nitrite oxidation …

Long-term fertilization is known to impact the biodiversity and community structures of soil
organisms, which are responsible for multiple soil ecosystem functions (multifunctionality) …

Chemolithotrophic ammonia-oxidizing bacteria and Thaumarchaeota are central players in
the global nitrogen cycle. Obligate ammonia chemolithotrophy has been characterized for …

Microbe-driven nitrification is a key process that affects nitrogen (N) utilization by plants and
N loss to the environment in agro-ecosystems. Ammonia-oxidizing bacteria (AOB) and …

Many wastewater treatment plants in the world do not remove reactive nitrogen from
wastewater prior to release into the environment. Excess reactive nitrogen not only has a …

Ammonia-and nitrite-oxidizing microorganisms are collectively responsible for the aerobic
oxidation of ammonia via nitrite to nitrate and have essential roles in the global …
