Aerobic nitrification of ammonia to nitrite and nitrate is a key process in the oceanic nitrogen cycling mediated by prokaryotes. Apart from Bacteria belonging to the β- and γ-Proteobacteria involved in the first nitrification step, Crenarchaeota have recently been recognized as main drivers of the oxidation of ammonia to nitrite in soil as well as in the ocean, as indicated by the dominance of archaeal ammonia monooxygenase (amoA) genes over bacterial amoA. Evidence is accumulating that… 

A new conceptual model of nitrification: a key factor in resolving the metabolic state of the ocean

Until the last decades, nitrification has been considered to occur only in the dark ocean. However, recent studies report nitrification within the euphotic zone, varying with differences in

High diversity of microplankton surrounds deep-water coral reef in the Norwegian Sea.

TLDR
Community profiling and analysis of ribosomal RNA gene sequences from a coral reef system at 350 m depth in the Norwegian Sea revealed a rich diversity of Eukarya and Bacteria and a moderate diversity of Archaea and the inferred function of dominant community members suggested autotrophs that utilise light, ammonium or sulphide, and lifestyles based on host associations.

Diversity, abundance and distribution of amoA-encoding archaea in deep-sea methane seep sediments of the Okhotsk Sea.

TLDR
The affiliation of certain archaeal amoA sequences to the GenBank sequences originally obtained from deep-sea hydrothermal vent environments indicated that the related AEA either have a wide range of temperature adaptation or they have a thermophilic evolutionary history in the modern cold deep- sea sediments of the Okhotsk Sea.

Decadal vision in oceanography 2021: Deep ocean

Focusing on the deep ocean, in this article, we summarize the existing research topics and discuss the direction and significance of future research. We focused on the ocean biogeochemical cycle in

Metatranscriptomic analysis of ammonia-oxidizing organisms in an estuarine bacterioplankton assemblage

TLDR
Low diversity within sequences assigned to most individual MG1C open reading frames (ORFs) and high homology with ‘Candidatus Nitrosopumilus maritimus’ strain SCM1 genome sequences were revealed, suggesting an enhanced response to oxidative stress by theMG1C population.

TLDR
The analysis presented here briefly considers the occur- rence and metabolism of other autotrophs sensu lato, i.e. not just the organisms with an autotrophic inorganic carbon assimilation machinery, and whether these organisms influence food webs by increasing the rate, or efficiency, of conversion of dissolved organic carbon ultimately derived from autotulent inorganiccarbon assimilation into particulate organic carbon.

Abundance and Diversity of Nitrifying Microorganisms in Marine Recirculating Aquaculture Systems

TLDR
Although comammox Nitrospira cannot be detected by 16S rRNA-based analysis, the high diversity and abundance of NOB that were detected in high-temperature samples indicated the prospective possibility of the occurrence of complete ammonia oxidation at high temperatures.

Archaeal lipids trace ecology and evolution of marine ammonia-oxidizing archaea.

Archaeal membrane lipids are widely used for paleotemperature reconstructions, yet these molecular fossils also bear rich information about ecology and evolution of marine ammonia-oxidizing archaea

Exaggerated trans-membrane charge of ammonium transporters in nutrient-poor marine environments

TLDR
Altered Amt sequence amino acid distribution from deep marine samples compared to variants sampled from shallow water in two important microbial lineages of the marine water column community indicates an evolutionary pressure towards an increasing dipole in Amt for these clades in deep ocean environments and is predicted to generate stronger electric fields facilitating ammonium acquisition.
