The sensitivity of marine N2 fixation to dissolved inorganic nitrogen [PDF]
Frontiers in Microbiology, 2012 The dominant process adding nitrogen (N) to the ocean, di-nitrogen (N2) fixation, is mediated by prokaryotes (diazotrophs) sensitive to a variety of environmental factors.

Diazotrophs and N2-Fixation Associated With Particles in Coastal Estuarine Waters [PDF]
Frontiers in Microbiology, 2018 Putative heterotrophic bacteria carrying out N2-fixation, so-called non-cyanobacterial diazotrophs (NCDs), are widely distributed in marine waters, but details of how the O2-inhibited N2-fixation process is promoted in the oxic water column remains ...

High N2 fixation rates in mycorrhizal tubercles on pine roots [PDF]
GeodermaTuberculate ectomycorrhizae (tubercles) are a type of mycorrhizal association, in which the fungus and root combine to form nodular structures. Diazotrophs associated with these structures could fix atmospheric N2 and contribute to N supply for plants in

Science, 2012 Microbiology![Figure][1] CREDITS (TOP AND MIDDLE): BURKHARD BUDEL; (BOTTOM) BETTINA WEBER Lichen-covered buildings, rocks, and trees are a common sight. Indeed, if they remain static for long enough, or simply grow slowly, most objects on Earth's surface become coated by cyanobacteria, algae, fungi, lichens, and bryophytes. These coatings are called

Implicating the Role of Au-H Bonds in Photochemical N2 Fixation by Ruthenium Doped Gold Clusters [PDF]
, 2023 Dinitrogen fixation through the Nitrogen Reduction Reaction (NRR) under mild conditions without the use of sacrificial agents has its share of formidable hurdles. It has been shown recently that Ru-doped Au nanoclusters can reduce N2 molecule to NH3 only

Nitrogen fixation in the western English Channel (NE Atlantic Ocean) [PDF]
, 2009 In temperate Atlantic waters (18.8 to 20.1°C), biological nitrogen fixation has beendemonstrated by 2 independent measurements: 15N-N2 incorporation and nifH identification in theDNA and expressed messenger RNA (mRNA).

mBio, 2015 The ability to reduce atmospheric nitrogen (N2) to ammonia, known as N2 fixation, is a widely distributed trait among prokaryotes that accounts for an essential input of new N to a multitude of environments.

Interactions between CCM and N2 fixation in Trichodesmium [PDF]
Photosynthesis Research, 2010 In view of the current increase in atmospheric pCO(2) and concomitant changes in the marine environment, it is crucial to assess, understand, and predict future responses of ecologically relevant phytoplankton species. The diazotrophic cyanobacterium Trichodesmium erythraeum was found to respond strongly to elevated pCO(2) by increasing growth ...

Molecular evidence for sediment nitrogen fixation in a temperate New England estuary [PDF]
PeerJ, 2016 Primary production in coastal waters is generally nitrogen (N) limited with denitrification outpacing nitrogen fixation (N2-fixation). However, recent work suggests that we have potentially underestimated the importance of heterotrophic sediment N2 ...

Direct biological fixation provides a freshwater sink for N2O
Nature Communications, 2023 Nitrous oxide (N2O) is a potent climate gas, with its strong warming potential and ozone-depleting properties both focusing research on N2O sources. Although a sink for N2O through biological fixation has been observed in the Pacific, the regulation of ...
