利用N-15自然丰度法研究固氮植物生物固氮量

A Review on quantifying biological nitrogen fixation based on N-15 natural abundance method

而某些微生物却可以直接利用占大气79%的氮气，即生物固氮，生物固氮是某些微生物利用体内的固氮酶将空气中的N2还原为氨的过程，它是自然界氮素循环的重要环节。

However , some microorganism can use the nitrogen directly which account for 79 % of the atmosphere , called biological nitrogen fixation , which means the deoxidize procession from nitrogen into N2 with the nitrogenase of the microorganism .

豆科植物的根瘤固氮占生物固氮总量的40%。

Nitrogen fixed by legume root nodules accounts for 40 % of total biological nitrogen fixation .

综述了植物内生固氮菌生物多样性、生物学特性，生理特性，与寄主植物的相互作用及应用前景等方面的研究进展。

Biodiversity , biological , physiological properties , mutual action with host plant , and application prospect of endophytic diazotroph and other aspects were summarized in this paper .

本文从固氮资源的发掘和利用、固氮的遗传工程以及固氮酶生物化学和化学模拟生物固氮三方面对国内外的研究进展进行了全面的阐述，并对生物固氮研究的前景进行了展望。

The paper reviews home and overseas research works on exhumation and use of nitrogen-fixing resource , genetics engineering of nitrogen fixation , and biochemistry of nitrogenase and chemical modeling of biological nitrogen fixation , and describe the prospect of biological nitrogen-fixing research .
