Diazotrophic Macroalgal Associations With Living and Decomposing Sargassum

Frontiers in Microbiology, 2018
Despite several studies reporting diazotrophic macroalgal associations (DMAs), biological nitrogen fixation (BNF) is still largely overlooked as a potential source of nitrogen (N) for macroalgal productivity. We investigated the role of BNF, via the acetylene reduction method, throughout different life stages of the invasive macroalga, Sargassum ...

Describing the Fate of Diazotroph-derived New Nitrogen

, 2014
Marine diazotrophs play an important role in marine biogeochemical cycles by fixing N2 into bioavailable forms, thus sustaining oceanic productivity over broad timescales through maintenance of bioavailable nitrogen stores.

Cold seep nitrogen fixation and its potential relationship with sulfur cycling

Microbiology Spectrum
Dinitrogen (N2) fixation is a crucial source of bioavailable nitrogen in carbon-dominated cold seep systems. Previous studies have shown that diazotrophy is not necessarily dependent on sulfate-dependent anaerobic oxidation of methane for energy, and ...

The genome of the endophytic bacterium H. frisingense GSF30T identifies diverse strategies in the Herbaspirillum genus to interact with plants

Frontiers in Microbiology, 2013
The diazotrophic, bacterial endophyte Herbaspirillum frisingense GSF30T has been identified in biomass grasses grown in temperate climate, including the highly nitrogen-efficient grass Miscanthus.

Fronts divide diazotroph communities in the Southern Indian Ocean. [PDF]

FEMS Microbiol Ecol
International audienceDinitrogen (N2) fixation represents a key source of reactive nitrogen in marine ecosystems. While the process has been rather well-explored in low latitudes of the Atlantic and Pacific Oceans, other higher latitude regions and ...

Planetary structure and drivers of diazotroph communities reveal key reservoirs of nitrogen-fixation potential

Biological nitrogen fixation sustains productivity across Earth's ecosystems, yet the diversity, distribution and ecological drivers of nitrogen-fixing prokaryotes (diazotrophs) remain incompletely resolved.

N2 fixation rate and diazotroph community structure in the western tropical North Pacific Ocean [PDF]

, 2019
(#br)In the present study, we report N2 fixation rate (15N isotope tracer assay) and the diazotroph community structure (using the molecular method) in the western tropical North Pacific Ocean (WTNP) (13°–20°N, 120°–160°E).

Temporal changes in the diazotrophic bacterial communities associated with Caribbean sponges Ircinia stroblina and Mycale laxissima

Frontiers in Microbiology, 2014
Sponges that harbor microalgal or cyanobacterial symbionts may benefit from photosynthetically derived carbohydrates, which are rich in carbon but devoid of nitrogen, and may therefore encounter nitrogen limitation.

Responses of Salt Marsh Plant Rhizosphere Diazotroph Assemblages to Drought

, 2018
Drought has many consequences in the tidally dominated Spartina sp. salt marshes of the southeastern US; including major dieback events, changes in sediment chemistry and obvious changes in the landscape.

Nitrogen Fixation, Carbohydrate Contents, and Bacterial Microbiota in Unelongated Stem of Manure Compost-Applied Rice at Panicle Initiation

Microbiology Research
In rice, symbiotic N2 fixation via nodule bacteroids does not take place naturally. Although N2 fixation by endophytic and associative diazotrophs has been reported in rice, the main organs and seasonal regulation for the N2 fixation have not been ...
