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.

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.

Symbiotic Nitrogen Fixation and the Challenges to Its Extension to Nonlegumes [PDF]

open access: yes, 2016
Access to fixed or available forms of nitrogen limits the productivity of crop plants and thus food production. Nitrogenous fertilizer production currently represents a significant expense for the efficient growth of various crops in the developed world.

How many metals does it take to fix N2? A mechanistic overview of biological nitrogen fixation [PDF]

open access: yes, 2006
During the process of biological nitrogen fixation, the enzyme nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Nitrogenase consists of two component metalloproteins, the iron (Fe) protein and the molybdenum-iron (MoFe) protein;

Nitrogen Yields and Biological Nitrogen Fixation of Winter Grain Legumes

open access: yesAgronomy, 2021
Grain legumes are valuable sources of protein and contribute to the diversification and sustainability of agricultural systems. Shifting the sowing date from spring to autumn is a strategy to address low yields of spring grain legumes under conditions of

Systematic identification of endogenous strong constitutive promoters from the diazotrophic rhizosphere bacterium Pseudomonas stutzeri DSM4166 to improve its nitrogenase activity

open access: yesMicrobial Cell Factories, 2023
Background Biological nitrogen fixation converting atmospheric dinitrogen to ammonia is an important way to provide nitrogen for plants. Pseudomonas stutzeri DSM4166 is a diazotrophic Gram-negative bacterium isolated from the rhizosphere of cereal ...

A secular increase in continental crust nitrogen during the Precambrian [PDF]

open access: yes, 2017
Recent work indicates the presence of substantial geologic nitrogen reservoirs in the mantle and continental crust. Importantly, this geologic nitrogen has exchanged between the atmosphere and the solid Earth over time. Changes in atmospheric nitrogen (i.

Biological nitrogen in modern agriculture

open access: yesPlant Varieties Studying and Protection, 2018
The value of biological fixation of air molecular nitrogen in the nitrogen feeding of agricultural crops and enrichment of soils is considered. High priority is paid to the economic and environmental significance of biological nitrogen.
