The nitrogenase of rhizomes was also determined and results implied the changes of nitrogenase might be owing to inoculation of Anabaena azotica Ley.

分析了接种菌种后羊草根际土壤固氮酶活的变化,接种固氮蓝藻能促进根际菌构成发生变化,进而影响植物的生长。

The octamer formation in vivo is related to cell growth process. During the log-phase of cell growth, the specific activity of nitrogenase is increasing, and the tetramer is the major form of molybdenum-iron protein.

在细胞生长过程中,胞内钼铁蛋白两种聚合体的相对含量出现规律性变化:在对数期,细胞固氮酶比活力成上升趋势,而钼铁蛋白主要以高活力的四聚体形式存在;在对数期结束至稳定期,细胞固氮酶比活力下降至一个低水平的稳定值,此时的钼铁蛋白基本上为八聚体形态。
