Excess labile carbon promotes diazotroph abundance in heat-stressed octocorals

open access: yesRoyal Society Open Science, 2023
Nitrogen limitation is the foundation of stable coral-algal symbioses. Diazotrophs, prokaryotes capable of fixing N2 into ammonia, support the productivity of corals in oligotrophic waters, but could contribute to the destabilization of holobiont ...

Dynamics of diazotroph particle colonization in the Arctic Ocean. [PDF]

open access: yesISME J
Abstract Global warming is causing sea ice retreat and intensifying algal blooms in the Arctic Ocean, in turn increasing nitrogen limitation in surface waters. Dinitrogen fixation by diazotrophic microorganisms, usually favored in low reactive nitrogen systems, may become an increasingly important source of nitrogen in the Arctic ...

Genetic and physiological insights into the diazotrophic activity of a non-cyanobacterial marine diazotroph [PDF]

open access: yesEnvironmental Microbiology, 2022
Abstract Nitrogen (N 2 ) fixation, or diazotrophy, supports a large part of primary production in oceans. Culture-independent approaches highlighted the presence in abundance of marine non-cyanobacterial diazotrophs (NCD) but their ecophysiology remains elusive, mostly because of ...

Overlooked and widespread pennate diatom-diazotroph symbioses in the sea [PDF]

open access: yes, 2022
\ua9 2022, The Author(s). Persistent nitrogen depletion in sunlit open ocean waters provides a favorable ecological niche for nitrogen-fixing (diazotrophic) cyanobacteria, some of which associate symbiotically with eukaryotic algae.

Assessing the Effect of Slope Position on the Community Assemblage of Soil Diazotrophs and Root Arbuscular Mycorrhizal Fungi

open access: yesJournal of Fungi, 2023
Considering the crucial role of soil diazotrophs and root arbuscular mycorrhizal fungi (AMF) in soil nutrient cycling during ecosystem restoration, diazotroph and AMF communities may be determined by slope position.

Land use alters diazotroph community structure by regulating bacterivores in Mollisols in Northeast China

open access: yesFrontiers in Microbiology, 2022
Changes in land use can generate environmental pressures that influence soil biodiversity, and numerous studies have examined the influences of land use on the soil microbial communities.

Draft Genome Sequences of Switchgrass Diazotrophs

open access: yesMicrobiology Resource Announcements, 2021
We report the draft genome sequences of five native nitrogen-fixing bacteria associated with roots of switchgrass isolated from the Tallgrass Prairies of Oklahoma. Nitrogen-fixing genes, including the nif cluster, are conserved across the Klebsiella and Kosakonia ...

Diazotrophy in the Indian Ocean: Current understanding and future perspectives

open access: yesLimnology and Oceanography Letters, 2023
Dinitrogen (N2) fixation provides the major source of reactive nitrogen in the open ocean, sustaining biological productivity. The Indian Ocean (IO) covers 22% of the ocean surface, while it only represents 1% of the global diazotroph database.

Symbioses of Cyanobacteria in Marine Environments: Ecological Insights and Biotechnological Perspectives

open access: yesMarine Drugs, 2021
Cyanobacteria are a diversified phylum of nitrogen-fixing, photo-oxygenic bacteria able to colonize a wide array of environments. In addition to their fundamental role as diazotrophs, they produce a plethora of bioactive molecules, often as secondary ...

Microalgal and Nitrogen-Fixing Bacterial Consortia: From Interaction to Biotechnological Potential

open access: yesPlants, 2023
Microalgae are used in various biotechnological processes, such as biofuel production due to their high biomass yields, agriculture as biofertilizers, production of high-value-added products, decontamination of wastewater, or as biological models for ...
