Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Net-zero emission and self-sustaining carbon-neutral have been widely encouraged and
intensively explored in wastewater treatment, as the wastewater industry accounts for …

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 …

Largely removed from anthropogenic delivery of nitrogen (N), Antarctica has notably low
levels of nitrogen. Though our understanding of biological sources of ammonia have been …

Microbial metabolism powers biogeochemical cycling in Earth's ecosystems. The taxonomic
composition of microbial communities varies substantially between environments, but the …

The recent recovery of genomes for organisms from phyla with no isolated representative
(candidate phyla) via cultivation-independent genomics enabled delineation of major new …

Ammonia-oxidizing archaea (AOA) are one of the most abundant groups of microbes in the
world's oceans and are key players in the nitrogen cycle. Their energy metabolism—the …

Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

Ocean microbes drive biogeochemical cycling on a global scale. However, this cycling is
constrained by viruses that affect community composition, metabolic activity, and …

Aerobic ammonium oxidizing bacteria were first isolated more than 100 years ago and
hydroxylamine is known to be an intermediate. The enzymatic steps involving …
