The Unique Biogeochemical Signature of the Marine Diazotroph Trichodesmium [PDF]

Frontiers in Microbiology, 2012
The elemental composition of phytoplankton can depart from canonical Redfield values under conditions of nutrient limitation or production (e.g., N fixation). Similarly, the trace metal metallome of phytoplankton may be expected to vary as a function of both ambient nutrient concentrations and the biochemical processes of the cell.

Nitrogen Fixation and Diazotrophs – A Review

Romanian Biotechnological Letters, 2021
Nitrogen fixation involves formation of ammonium from N2, which needs a high input of energy. Biological nitrogen fixation utilizes the enzyme nitrogenase and ATP to fix nitrogen. Nitrogenase contains a Fe-protein and a Mo-Fe-protein and other metal cofactors.

Multiomic Approaches Reveal Hormonal Modulation and Nitrogen Uptake and Assimilation in the Initial Growth of Maize Inoculated with Herbaspirillum seropedicae

Plants, 2022
Herbaspirillum seropedicae is an endophytic bacterium that can fix nitrogen and synthesize phytohormones, which can lead to a plant growth-promoting effect when used as a microbial inoculant.

Taxonomy and Phylogeny of Diazotrophs

, 1998
The biodiversity of nitrogen-fixing organisms is huge. Taxonomic and phylogenetic research is needed to structure this diversity, to facilitate communication among scientists, and to increase our understanding of the evolution and biology of diazotrophs.

Diazotroph Genomes and Their Seasonal Dynamics in a Stratified Humic Bog Lake

Frontiers in Microbiology, 2020
Aquatic N-fixation is generally associated with the growth and mass development of Cyanobacteria in nitrogen-deprived photic zones. However, sequenced genomes and environmental surveys suggest active aquatic N-fixation also by many non-cyanobacterial ...

Promotion of Nitrogen Fixation of Diverse Heterotrophs by Solid-Phase Humin

Frontiers in Microbiology, 2022
Although biological nitrogen fixation (BNF) proceeds under mild conditions compared to the energy-intensive Haber–Bosch process, the slow kinetics of BNF necessitate the promotion of BNF activity in its practical application.

Co-Inoculation with Bradyrhizobium and Humic Substances Combined with Herbaspirillum seropedicae Promotes Soybean Vegetative Growth and Nodulation

Agronomy, 2023
The effect of humic substances (HSs) in combination with or without plant-growth-promoting bacteria on soybean vegetative growth and root nodulation was examined in this study.

Phyllosphere of Cotton as a Habitat for Diazotrophic Microorganisms [PDF]

Applied and Environmental Microbiology, 1984
Positive nitrogenase activities ranging from 0.18 to 0.78 nmol of C 2 H 4 cm −2 h −1 were detected on the leaf surfaces of different varieties of cotton ( Gossypium hirsutum L. and G. herbaceum L.)

Global marine metagenomics reveals the functional diversity and ecological adaptations of diazotrophs across marine ecosystems

Communications Earth & Environment
Biological nitrogen fixation by diazotrophs is vital for nitrogen supply and marine productivity. Despite extensive documentation of diverse diazotrophs, their functional diversity and adaptive strategies across ecosystems remain largely underexplored ...
