The Assimilation of Diazotroph-Derived Nitrogen by Scleractinian Corals Depends on Their Metabolic Status

, 2017
International audienceTropical corals are associated with a diverse community of dinitrogen (N2)-fixing prokaryotes (diazotrophs) providing the coral an additional source of bioavailable nitrogen (N) in oligotrophic waters.

Soil microclimate and vegetation dynamics shape elevational and seasonal variations of diazotrophic communities in alpine grasslands

Frontiers in Plant Science
IntroductionDiazotrophs play critical roles in maintaining ecosystem nitrogen (N) cycling in alpine grasslands. However, the elevational and seasonal variations of diazotrophic communities in these ecosystems remain poorly understood.

Diazotrophic bacteria in star flowers

Bioscience Journal, 2012
This study evaluated the occurrence and density of associative diazotrophic bacteria in the rhizosphere, collar, roots and leaves of Syngonanthus elegans (Bong) Ruhland (Goldenfoot) and Syngonanthus aciphyllus (Mini-skirt). These species are able to grow in poor soils. Five samples, with 25 plants both of S. elegans and S.

Bacterial Isolation from Natural Grassland on Nitrogen-Free Agar Yields Many Strains Without Nitrogenase

Microorganisms
Nitrogen inputs for sustainable crop production for a growing population require the enhancement of biological nitrogen fixation. Efforts to increase biological nitrogen fixation include bioprospecting for more effective nitrogen-fixing bacteria.

Spatial-temporal variability in diazotroph assemblages in Chesapeake Bay using an oligonucleotide nifH microarray

, 2007
The distribution of nitrogen-fixing microorganisms in the Chesapeake Bay was investigated using fingerprints from a nifH microarray comprised of 706 60-mer oligonucleotide nifH probes representing cultivated organisms and environmental clones from ...
