生物固氮

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 .
