Diazotroph-derived nitrogen release and transfer under varying light intensity: insights from co-culture studies [PDF]

Biological dinitrogen (N2) fixation is a major source of new N to surface seawater, sustaining ocean productivity. However, the fate of diazotroph-derived nitrogen (DDN), specifically its release and transfer, and the factors controlling these processes,

Ectomycorrhizal fungi significantly shape endorhizal bacteria associated with Pinus taiwanensis in heavy metal soils

Ecosphere
The understanding of ectomycorrhizal (ECM) fungi's role in shaping bacterial groups and regulating heavy metals in soils was limited in the past. A mesocosm experiment with inoculation treatments (Pezicula ericae K2 and Pisolithus tinctorius) was applied

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 ...

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.

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.

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.

The Madagascar Bloom – a serendipitous study [PDF]

, 2013
The late austral summer (February-April) phytoplankton bloom that occurs east of Madagascar exhibits significant interannual variability and at its largest extent covers ~1% of the world’s ocean surface area.

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 ...
