The marine nitrogen (N) cycle controls the productivity of the oceans. This cycle is driven by complex biogeochemical transformations, including nitrogen fixation, denitrification, and assimilation and anaerobic ammonia oxidation, mediated by microorganisms. New processes and organisms continue to be discovered, complicating the already complex picture of oceanic N cycling. Genomics research has uncovered the diversity of nitrogen metabolism strategies in phytoplankton and bacterioplankton. The…

Diversity, ecology and evolution of marine diazotrophic microorganisms
Biological N2 fixation, the reduction of dinitrogen (N2) gas to biologically available nitrogen, is a fundamental process since it represents a source of new nitrogen for marine life in areas where
Lipids as paleomarkers to constrain the marine nitrogen cycle
The recent advances in marine nitrogen cycle lipid biomarkers are emphasised, the missing links still needed to fully elucidate past shifts in this biogeochemically‐important cycle are underlined, and examples of biomarker applications in the geological past are provided.
Direct Utilization of Organic Nitrogen by Phytoplankton and Its Role in Nitrogen Cycling Within the Southern California Bight
Datoms are demonstrated to have an ability to efficiently scavenge urea in situ, allowing certain diatoms to outcompete the rest of the community and alter the current view of microbial food webs.

The inextricable link between the P cycle and cycles of other bioelements predicts future impacts on, for example, nitrogen fixation and carbon dioxide sequestration.
Biological N2O Fixation in the Eastern South Pacific Ocean and Marine Cyanobacterial Cultures
The findings presented here indicate that assimilative N2O fixation takes place under extreme environmental conditions (i.e., light, nutrient, oxygen) where both autotrophic and heterotrophic microbes appear to be involved, which could provide a globally significant sink for atmospheric N 2O which in turn affects the oceanic N2 O inventory and may also represent a yet unexplored global oceanic source of fixed N.
A multi-omics approach to microbial nitrogen and sulfur cycling in the oxygen starved ocean
Microbial communities mediate biogeochemical processes of Carbon (C), Nitrogen (N) and Sulfur (S) cycling in the ocean on global scales. Oxygen (O2) availability is a key driver in these processes
Five decades of N2 fixation research in the North Atlantic Ocean
Dinitrogen (N2) fixation (the reduction of atmospheric N2 to ammonium by specialized prokaryotic microbes), represents an important input of fixed nitrogen and contributes significantly to primary
Microbial oceanography of anoxic oxygen minimum zones
New analytical technologies are revealing vanishingly low oxygen concentrations in nitrite-rich OMZs, indicating that these AMZs are essentially anoxic marine zones (AMZs), and previously unrecognized episodic intrusions of oxygen into the AMZ core are revealed, which could periodically support aerobic metabolisms in a typically anoxic environment.
Ecological Energetic Perspectives on Responses of Nitrogen-Transforming Chemolithoautotrophic Microbiota to Changes in the Marine Environment
This article examines major groups of chemolithoautotrophic microorganisms that participate in the marine nitrogen cycle and examines their eco-energetic strategies, contributions to carbon cycling, and putative responses to and impacts on the various global change processes associated with global warming, ocean acidification, eutrophication, deoxygenation, and pollution.

Lam et al. (5) used a suite of approaches to tackle anammox in the Peruvian OMZ and discovered how anamm ox requirements could be supported by other nitrogen transformations, but they added yet another nitrogen transformation to the oceanic nitrogen cycle mix: dissimilatory nitrate reduction to ammonia.
Deep-Sea Archaea Fix and Share Nitrogen in Methane-Consuming Microbial Consortia
It is shown that deep-sea anaerobic methane-oxidizing archaea fix N2, as well as structurally similar CN–, and share the products with sulfate-reducing bacterial symbionts, and reveals a link between the global carbon, nitrogen, and sulfur cycles.
Evolution of the nitrogen cycle and its influence on the biological sequestration of CO2 in the ocean
Over geological time, photosynthetic carbon fixation in the oceans has exceeded respiratory oxidation of organic carbon. The imbalance between the two processes has resulted in the simultaneous
Production of N2 through Anaerobic Ammonium Oxidation Coupled to Nitrate Reduction in Marine Sediments
It is found that a process novel to the marine nitrogen cycle, anaerobic oxidation of ammonium coupled to nitrate reduction, contributes substantially to N2 production in marine sediments.

It is shown that instead, the anammox process (the anaerobic oxidation of ammonium by nitrite to yield N2) is mainly responsible for nitrogen loss in the OMZ waters of one of the most productive regions of the world ocean, the Benguela upwelling system.
Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
Evidence for bacteria that anaerobically oxidize ammonium with nitrite to N2 in the world's largest anoxic basin, the Black Sea is provided and anammox bacteria have been identified and directly linked to the removal of fixed inorganic nitrogen in the environment.
Spatial coupling of nitrogen inputs and losses in the ocean
It is concluded that oceanic nitrogen fixation is closely tied to the generation of nitrogen-deficient waters in denitrification zones, supporting the view that nitrogen fixation stabilizes the oceanic inventory of fixed nitrogen over time.
Unicellular Cyanobacterial Distributions Broaden the Oceanic N2 Fixation Domain
It is found that two major groups of unicellular N2-fixing cyanobacteria (UCYN) have distinct spatial distributions that differ from those of Trichodesmium, the N2+ cyanobacterium previously considered to be the most important contributor to open-ocean N2 fixation.
Unicellular cyanobacteria fix N2 in the subtropical North Pacific Ocean
It is shown that there are unicellular cyanobacteria in the open ocean that are expressing nitrogenase, and are abundant enough to potentially have a significant role in N dynamics.
Metabolic streamlining in an open-ocean nitrogen-fixing cyanobacterium
It is found that UCYN-A lacks a number of major metabolic pathways including the tricarboxylic acid cycle, but retains sufficient electron transport capacity to generate energy and reducing power from light, and is dependent on other organisms for essential compounds.
