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.

Moss-cyanobacteria associations as biogenic sources of nitrogen in boreal forest ecosystems

Frontiers in Microbiology, 2013
The biological fixation of atmospheric nitrogen (N) is a major pathway for available N entering ecosystems. In N-limited boreal forests, a significant amount of N2 is fixed by cyanobacteria living in association with mosses, contributing up to 50 % to ...

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 ...

Microbial protein out of thin air : fixation of nitrogen gas by an autotrophic hydrogen-oxidizing bacterial enrichment [PDF]

, 2020
For the production of edible microbial protein (MP), ammonia generated by the Haber-Bosch process or reclaimed ammonia from waste streams is typically considered as the nitrogen source.

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 ...

Nitrogen Fixing Azotobacter Species as Potential Soil Biological Enhancers for Crop Nutrition and Yield Stability

Frontiers in Microbiology, 2021
Biological nitrogen fixation (BNF) refers to a microbial mediated process based upon an enzymatic “Nitrogenase” conversion of atmospheric nitrogen (N2) into ammonium readily absorbable by roots.

Enhanced biological N2 fixation and yield of faba bean (Vicia faba L.) in an acid soil following biochar addition: dissection of causal mechanisms

Plant and Soil, 2015
Background and aimsAcid soils constrain legume growth and biochars have been shown to address these constraints and enhance biological N2 fixation in glasshouse studies.

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.
