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 …

Methane is the main component of natural gas and biogas. As an abundant energy source,
methane is crucial not only to meet current energy needs but also to achieve a sustainable …

The discovery of ammonia oxidation by mesophilic and thermophilic Crenarchaeota and the
widespread distribution of these organisms in marine and terrestrial environments indicated …

Soil microorganisms play a critical role in the biosphere, and the influence of cropland
fertilization on the evolution of soil as a living entity is being actively documented. In this …

Ammonia-oxidizing archaea (AOA) are among the most abundant microorganisms and key
players in the global nitrogen and carbon cycles. They share a common energy metabolism …

There is growing evidence that phages with unusually large genomes are common across
various microbiomes, but little is known about their genetic inventories or potential …

As part of an ongoing survey of microbial community gene expression in the ocean, we
sequenced and compared∼ 38 Mbp of community transcriptomes and∼ 157 Mbp of …

It is well known that the ratio of ammonia-oxidizing archaea (AOA) and bacteria (AOB)
ranges widely in soils, but no data exist on what might influence this ratio, its dynamism, or …

The complete genome of the ammonia-oxidizing bacterium Nitrosospira multiformis (ATCC
25196T) consists of a circular chromosome and three small plasmids totaling 3,234,309 bp …

Planktonic Crenarchaea are thought to play a key role in chemolithotrophic ammonia
oxidation, a critical step of the marine nitrogen (N) cycle. In this study, we examined the …
