Optimizing Initial Nitrogen Application Rates to Improve Peanut (Arachis hypogaea L.) Biological Nitrogen Fixation

open access: yesAgronomy, 2023
The application of nitrogen fertilizer is crucial to the growth and biological nitrogen fixation of peanut, especially in the seedling stage where nodules have not yet formed.

Biological Nitrogen Fixation and Nitrogen Accumulation in Peatlands

open access: yesFrontiers in Earth Science, 2022
Peatlands cover about 3% of the Earth’s surface and are regarded as a vital carbon (C) pool and sink. The formation of peatland is supported by continuously supplied nitrogen (N) but the sources of this N remain unclear.

Active Nitrogen Fixation by Iron-Reducing Bacteria in Rice Paddy Soil and Its Further Enhancement by Iron Application

open access: yesApplied Sciences, 2023
In rice paddy soil, biological nitrogen fixation is important for sustaining soil nitrogen fertility and rice growth. Anaeromyxobacter and Geobacteriaceae, iron-reducing bacteria belonging to Deltaproteobacteria, are newly discovered nitrogen-fixing ...

Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii

open access: yesMicrobiology Spectrum, 2023
Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering

An engineered, non-diazotrophic cyanobacterium and its application in bioelectrochemical nitrogen fixation

open access: yesCell Reports Physical Science, 2021
Summary: The reduction of chemically inert nitrogen to ammonia is a critical step in the global nitrogen cycle. Microbial nitrogen fixation is a promising way to realize nitrogen reduction and ammonia production at mild conditions.

Regulation of Biological Nitrogen Fixation [PDF]

open access: yesThe Journal of Nutrition, 2000
Biological nitrogen fixation, a process found only in some prokaryotes, is catalyzed by the nitrogenase enzyme complex. Bacteria containing nitrogenase occupy an indispensable ecological niche, supplying fixed nitrogen to the global nitrogen cycle. Due to this inceptive role in the nitrogen cycle, diazotrophs are present in virtually all ecosystems ...

Isolation, identification and characterization of nitrogen fixing endophytic bacteria and their effects on cassava production [PDF]

open access: yesPeerJ, 2022
Background Cassava (Manibot esculenta Crantz) is one of the most important among tuber crops. The amount of nitrogen fertilizer used for cassava production is relatively high (400 kg ha−1), but there are few studies on biological nitrogen fixation in ...

Rhamnolipid Enhances the Nitrogen Fixation Activity of Azotobacter chroococcum by Influencing Lysine Succinylation

open access: yesFrontiers in Microbiology, 2021
The enhancement of nitrogen fixation activity of diazotrophs is essential for safe crop production. Lysine succinylation (KSuc) is widely present in eukaryotes and prokaryotes and regulates various biological process.
