Bryophyte-cyanobacteria associations during primary succession in recently Deglaciated areas of Tierra del Fuego (Chile). [PDF]
PLoS ONE, 2014 Bryophyte establishment represents a positive feedback process that enhances soil development in newly exposed terrain. Further, biological nitrogen (N) fixation by cyanobacteria in association with mosses can be an important supply of N to terrestrial ...

Residual effects of successive exposure of soybean Bradyrhizobium strains to aluminium on solid defined medium [PDF]
Pesquisa Agropecuária Brasileira, 2001 The aim of these studies was to investigate whether residual toxic effects of exposing soybean root nodule bacteria to Al in a solid defined media (SDM) alter tolerance to Al, survival, sensitivity to antibiotics, N2 fixation effectiveness and genetic ...

The fate of N2O consumed in soils [PDF]
, 2007 Soils are capable to consume N2O. It is generally assumed that consumption occurs exclusively via respiratory reduction to N2 by denitrifying organisms (i.e. complete denitrification). Yet, we are not aware of any verification of this assumption.

A Molecular-Level Mechanism of the Biological N2 Fixation
, 2019 We present a detailed molecular-level mechanism for the biological fixation of atmospheric nitrogen into ammonia. The mechanism is based on a series of electronic structure calculations and provides insight into the key question of what it is that the ...

Variation in symbiotic N2 fixation rates among Sphagnum mosses.
PLoS ONE, 2020 Biological nitrogen (N) fixation is an important process supporting primary production in ecosystems, especially in those where N availability is limiting growth, such as peatlands and boreal forests.

Nitrogenases in Oxygen Minimum Zone Waters
Frontiers in Marine Science, 2022 Biological dinitrogen (N2) fixation is the pathway making the large pool of atmospheric N2 available to marine life. Besides direct rate measurements, a common approach to explore the potential for N2 fixation in the ocean is a screening-based targeting ...

Planktonic Aggregates as Hotspots for Heterotrophic Diazotrophy: The Plot Thickens
Frontiers in Microbiology, 2022 Biological dinitrogen (N2) fixation is performed solely by specialized bacteria and archaea termed diazotrophs, introducing new reactive nitrogen into aquatic environments.

Improving Biological Nitrogen Fixation to Improve Soil Nutrient Status
EDIS, 2023 The chemical reduction of atmospheric nitrogen (N2) by hydrogen for incorporation into plant tissue is known as N fixation. Along with the carbon, N has a role in maintaining the optimum source and sink ratio, which ensures crop growth and biological ...

Heterogeneity of nitrogen fixation in the mesopelagic zone of the South China Sea
Frontiers in Marine ScienceBiological dinitrogen (N2) fixation, the energetically expensive conversion of N2 gas to ammonia, plays an essential role in balancing the nitrogen budget in the ocean.
