Anthropogenic climate change may reduce global diazotroph diversity [PDF]
Nature CommunicationsClimate change impacts microbial community structure and function, thus altering biogeochemical cycles. Biological nitrogen fixation by diazotrophs is involved in maintaining the balance of the global nitrogen cycle, but the global biogeographic patterns

Frontiers in Marine ScienceMarine biological nitrogen fixation (BNF) is crucial for introducing “new nitrogen” into the oceans. Over the past 30 years, numerous laboratory and on-board culture experiments have been conducted studying the effects of nutrients such as total ...

Diazotrophs and N2-Fixation Associated With Particles in Coastal Estuarine Waters
Frontiers in Microbiology, 2018 Putative heterotrophic bacteria carrying out N2-fixation, so-called non-cyanobacterial diazotrophs (NCDs), are widely distributed in marine waters, but details of how the O2-inhibited N2-fixation process is promoted in the oxic water column remains ...

Diversity and Activity of Diazotrophs in Great Barrier Reef Surface Waters
Frontiers in Microbiology, 2017 Discrepancies between bioavailable nitrogen (N) concentrations and phytoplankton growth rates in the oligotrophic waters of the Great Barrier Reef (GBR) suggest that undetermined N sources must play a significant role in supporting primary productivity ...

nifH gene expression and diversity in geothermal springs of Tengchong, China
Frontiers in Microbiology, 2022 Terrestrial hot springs have been suggested to harbor diverse diazotrophic lineages by using DNA-based nifH gene phylogenetic analysis. However, only a small amount of diazotrophs were ever confirmed to perform nitrogen fixation.

Temporal dynamics of total and active root-associated diazotrophic communities in field-grown rice
Frontiers in Microbiology, 2022 Plant-associated nitrogen-fixing microorganisms (diazotrophs) are essential to host nutrient acquisition, productivity and health, but how host growth affects the succession characteristics of crop diazotrophic communities is still poorly understood ...

Can Top-Down Controls Expand the Ecological Niche of Marine N2 Fixers?
Frontiers in Microbiology, 2021 The ability of marine diazotrophs to fix dinitrogen gas (N2) is one of the most influential yet enigmatic processes in the ocean. With their activity diazotrophs support biological production by fixing about 100–200 Tg N/year and turning otherwise ...

DIAZOTROPH – BIOAGENT – PATHOGEN PANORAMA TOWARDS THE PRODUCTION OF ENVIRONMENTALLY SAFED CUCUMBER [PDF]
Journal of Agricultural Chemistry and Biotechnology, 2007 The interactions among some bacterial bioagents, diazotrophs and phytopathogenic fungi were in vitro examined adopting the dual plate culture technique.
