nitrogen fixation n 1.(Biology) the conversion of atmospheric nitrogen into nitrogen compounds by certain bacteria, such asRhizobiumin the root nodules of legumes 2.(Chemistry) a process, such as the Haber process, in which atmospheric nitrogen is converted into a nitrogen compound, used esp for...
It is a slow process. The nitrogen is mainly provided by the atmosphere and they make more than 80 percent of the air. The nitrogen can occur in the form of element or molecule. In the process of nitrogen fixation this nitrogen is changed into the other compounds of nitrogen. The ...

these bacteria could fix atmospheric nitrogen, there has been an intensification of studies relating to both the biochemistry and physiology of this process... BC Kelley,PM Vignais,J Meyer - 《Biochimie》 被引量: 189发表: 1978年 The biology and biochemistry of nitrogen fixation: a look forward...
The spectrum of organisms recognized to contribute to N 2 fixation in the sea has been greatly expanded, and there has been a virtual revolution in understanding of its quantitative significance, the interplay between N 2 fixation and the C cycle and the major controls on this process. 展开 ...
Also, cycads (a type of tropical plant that resembles a palm tree) produce special aboveground roots that harbor nitrogen-fixing cyanobacteria. By growing above the ground, the roots are exposed to sunlight, which the cyanobacteria require for growth. Nitrogen fixation by free-living bacteria in ...
To ensure success, BCM should (1) use dynamic baselines with control sites, (2) monitor the populations dynamics of a large array of vertebrate and invertebrate species, and (3) assign credits through an independent, transparent, and cost-effective validation process. T. Mitchell Aide Comment...
nitrogen transformation processes are related to each other, and together determine the balance and fate of nitrogen in the soil ecosystem. Nitrogen fixation is a process of reducing molecular nitrogen to ammonia and other nitrogen-containing compounds. It is one of the important methods of nitrogen...
Little was known about the electron donors in nitrogen fixation, the role of ATP in the process had not been shown, and nothing was known about the composition of the nitrogen fixing enzymes although it was assumed that they contained iron and molybdenum. It was of obvious importance to ...
