Light-limited growth rate modulates nitrate inhibition of dinitrogen fixation in the marine unicellular cyanobacterium Crocosphaera watsonii. [PDF]
PLoS ONE, 2014 Biological N2 fixation is the dominant supply of new nitrogen (N) to the oceans, but is often inhibited in the presence of fixed N sources such as nitrate (NO3-).

Viability of liquid medium-inoculation of Rhizobium etli in planting furrows with common bean [PDF]
Pesquisa Agropecuária Brasileira, 2018 : The objective of this work was to evaluate the viability of liquid medium inoculation of Rhizobium etli in the planting furrow and to certify the efficiency of its strain UFLA 02-100 as a potential inoculant for common bean (Phaseolus vulgaris).

Frontiers in Marine Science, 2022 Oxygen minimum zones (OMZs) have been suggested as a suitable niche for the oxygen-sensitive process of biological fixation of dinitrogen (N2) gas. However, most N2 fixation rates reported from such waters are low.

Dinitrogen fixation in aphotic oxygenated marine environments
Frontiers in Microbiology, 2013 We measured N2 fixation rates from oceanic zones that have traditionally been ignored as sources of biological N2 fixation; the aphotic, fully oxygenated, nitrate (NO3-)-rich, waters of the oligotrophic Levantine Basin (LB) and the Gulf of Aqaba (GA). N2

Nitrogen fixation and transportation by rhizobacteria: a scenario of rice and banana [PDF]
, 2010 Rhizobacteria can fix N2 in association with rice roots externally and internally and this fixed N2 is being utilized by the host plant. Nitrogen fixation and plant growth promotion by rhizobacteria might be important factors in achieving a sustainable ...

Diversity and Efficiency of Rhizobia Communities from Iron Mining Areas Using Cowpea as a Trap Plant
Revista Brasileira de Ciência do Solo, 2017 Mining is an important economic activity. However, its impact on environment must be accessed, mainly on relevant processes for their sustainability. The objective of this study was to evaluate the diversity and efficiency of symbiotic nitrogen fixing ...

Importance of N2-Fixation on the Productivity at the North-Western Azores Current/Front System, and the Abundance of Diazotrophic Unicellular Cyanobacteria. [PDF]
PLoS ONE, 2016 To understand the impact of the northwestern Azores Current Front (NW-AzC/AzF) system on HCO3--and N2-fixation activities and unicellular diazotrophic cyanobacteria (UCYN) distribution, we combined geochemical and biological approaches from the ...

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.

Bradyrhizobium strain and the 15N natural abundance quantification of biological N2 fixation in soybean [PDF]
Scientia Agricola, 2008 In commercial plantations of soybean in both the Southern and the Cerrado regions, contributions from biological nitrogen fixation (BNF) are generally proportionately high. When using the 15N natural abundance technique to quantify BNF inputs, it is essential to determine, with accuracy, the 15N abundance of the N derived from BNF (the 'B' value). This
