| 摘 要： | 由木麻黄（ＣａｓｕａｒｉｎａｅｇｕｉｓｅｔｉｆｏｌｉａＬ）根瘤中分离的内生菌ＦｒａｎｋｉａｓｐＣｅｌ５１７菌株，可在以丙酸为碳源的限定培养基中表现出较高的固氮酶活性。固氮周期在１８０ｈ达到高峰。蛋白胨与ＮＨ４Ｃｌ对固氮活性有抑制作用，氧分压为１０％～１５％时，固氮酶活性最高，泡囊的诱导时间对固氮酶活性影响较大。

| Abstract: | Frankia sp Cel 517 can show higher nitrogenase activity in a defined medium containing propionic acid as C_source. The maximal nitrogenase activity of Cel 517 arrived at 180 hours. Proteinase and NH 4Cl inhibited nitrogenase activity. The highest nitrogenase activity was obtained in 10%～15% of O 2. The time of induced vesicles has great influence on nitrogenase. |
