Hopanoid lipids may facilitate aerobic nitrogen fixation in the ocean. [PDF]

, 2019
Cyanobacterial diazotrophs are considered to be the most important source of fixed N2 in the open ocean. Biological N2 fixation is catalyzed by the extremely O2-sensitive nitrogenase enzyme.

Cyanobacteria as multifunctional bioinputs for sustainable intensification, soil health enhancement, and climate resilience in rice‐based cropping systems

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Ensuring food security goals through the provision of sustainable energy and food without compromising environmental sustainability is the current requirement amid threats from climate change, uncontrolled global population, and scarcity of natural resources.

N2 cleavage by silylene and formation of H2Si(μ-N)2SiH2

Nature Communications
Fixation and functionalisation of N2 by main-group elements has remained scarce. Herein, we report a fixation and cleavage of the N ≡ N triple bond achieved in a dinitrogen (N2) matrix by the reaction of hydrogen and laser-ablated silicon atoms. The four-

Doubling of marine dinitrogen-fixation rates based on direct measurements [PDF]

, 2012
Biological dinitrogen fixation provides the largest input of nitrogen to the oceans, therefore exerting important control on the ocean’s nitrogen inventory and primary productivity.

Evidence for efficient regenerated production and dinitrogen fixation in nitrogen-deficient waters of the South Pacific Ocean: impact on new and export production estimates [PDF]

Biogeosciences, 2008
One of the major objectives of the BIOSOPE cruise, carried out on the R/V Atalante from October-November 2004 in the South Pacific Ocean, was to establish productivity rates along a zonal section traversing the oligotrophic South Pacific Gyre (SPG ...

Five decades of N2 fixation research in the North Atlantic Ocean

Frontiers in Marine Science, 2015
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 productivity in the oceans.

Diiron Bridged-Thiolate Complexes That Bind N_2 at the Fe^(II)Fe^(II), Fe^(II)Fe^I, and Fe^IFe^I Redox States [PDF]

, 2015
All known nitrogenase cofactors are rich in both sulfur and iron and are presumed capable of binding and reducing N_2. Nonetheless, synthetic examples of transition metal model complexes that bind N_2 and also feature sulfur donor ligands remain scarce ...

Nitrogenase: A nucleotide-dependent molecular switch [PDF]

, 1994
In the simplest terms, the biological nitrogen cycle is the reduction of atmospheric dinitrogen (N2) to ammonia with the subsequent reoxidation ammonia to dinitrogen (1).
