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.

THE DIVERSITY, DISTRIBUTION AND POTENTIAL METABOLISM OF NON-CYANOBACTERIAL DIAZOTROPHS IN THE NORTH ATLANTIC OCEAN

, 2017
In large areas of the Atlantic Ocean, primary productivity is limited by fixed nitrogen. Biological N2 fixation, conducted by diazotrophs, contributes significantly to the input of new fixed nitrogen in those areas.

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.

Isolation and Characterization of Diazotrophic Bacteria from the Surface-Sterilized Roots of Some Legumes.

, 2003
A total of 251 bacteria were isolated using a nitrogen-free, malate-containing, semi-solid media (JNFb) from the surface-sterilized roots of eight species of legumes: Arachis hypogea, Astragalus sinicus, Crotalaria juncea, Glycine max, Medicago saliva ...

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.

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,

Monitoring the persistence of a genetically modified strain of the Azorhizobium caulinodans in the rhizosphere of Triticum aestivum L.

Biotecnología Vegetal, 2013
A protocol was developed to monitor persistence and spread of a genetically modified strain of the growth promoting diazotroph Azorhizobium caulinodans used to inoculate field grown wheat.
