The biological nitrogen fixation (BNF) is a way to eliminate the usage of chemical fertilizer and also to prevent the damage to the agricultural ecosystem. This paper reviews about the role of diazotrophs in agriculture. Azolla and Cyanobacteria can be able toKumar, S R...

Nitrogenase, the enzyme that catalyses biological nitrogen fixation, is oxygen sensitive and requires ATP and an electron donor for activity. The enzyme consists of two metalloprotein components — the Fe protein and the MoFe protein — which contain different metal clusters. Electron transfer from th...

Better understanding of rhizobial ecology and selection of inoculant strains as well as their target application regarding the environmental conditions of certain production area in one of many approaches to enhance the nitrogen fixation efficiency. 展开 ...
Nitrogen fixation is the primary source of reactive nitrogen in the ocean. Most ecological models do not predict nitrogen fixation in the Antarctic Ocean because of the low availability of iron and high abundance of nitrogen. Here we extensively examined nitrogen fixation in the Antarctic Ocean, and...
Nitrogen is the most important, limiting element for plant production. Biological nitrogen fixation is the only natural means to convert this essential element to a usable form.
The main outcomes of this review were (i) as NDFA increased, seed production per N2 fixation decreased (from 0.033 to 0.017 Mg yield kg–1 N from low, 28%, to high, 80%, NDFA); (ii) N-gap increased faster when NDFA values were above 80% and after plant N content was above 370...
