Nitrification, as a crucial step in nitrogen cycling and plant nutrition, is a biologically
mediated process responsible for enormous losses of nitrogen fertilizer and a contributor to …

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 …

Background Agricultural food production is at the base of food and fodder, with fertilization
having fundamentally and continuously increased crop yield over the last decades. The …

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

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

Nitrogen is essential for life on Earth. Soil biota are responsible for its accumulation,
persistence, and loss from ecosystems. Microbial nitrogen transformations include its …

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

Background Linking the identity of wild microbes with their ecophysiological traits and
environmental functions is a key ambition for microbial ecologists. Of many techniques that …

Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to
have been a central part of the global biogeochemical nitrogen cycle since the oxygenation …

The discovery of ammonia-oxidizing archaea (AOA), now generally recognized to exert
primary control over ammonia oxidation in terrestrial, marine, and geothermal habitats …
