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 …

Nitrification is the microbial conversion of reduced forms of nitrogen (N) to nitrate (NO3−),
and in fertilized soils it can lead to substantial N losses via NO3− leaching or nitrous oxide …

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 …

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 …

The gut microbiota can significantly affect the function of the intestinal barrier. Some
intestinal probiotics (such as Lactobacillus, Bifidobacteria, a few Escherichia coli strains, and …

Ammonia-oxidizing archaea (AOA) are among the most abundant and ubiquitous
microorganisms in the ocean, exerting primary control on nitrification and nitrogen oxides …

Microbial metabolism upholds a fundamental role in the sustainability of water ecosystems.
However, how microorganisms surviving in low-concentration substrate water environments …

Most prokaryotic cells are encased in a surface layer (S-layer) consisting of a paracrystalline
array of repeating lattice-forming proteins. S-layer proteins populate a vast and diverse …

Anaerobic ammonia-oxidizing (Anammox) bacteria (AnAOB) rely on nitrite supplied by
ammonia-oxidizing bacteria (AOB) and archaea (AOA). Affinities for ammonia and oxygen …

Ammonia oxidation, as the first step of nitrification, constitutes a critical process in the global
nitrogen cycle. However, fundamental knowledge of its key enzyme, the copper-dependent …
