螺旋藻胞内核酸酶活性研究

Research on Intracellular Nuclease Activity of Spirulina platensis

对钝顶螺旋藻A9品系进行实验研究,证明其具有较强活性的胞内核酸酶并实验研究了抑制其活性的方法。实验结果显示:在培养液中添加EDTA浓度为2～4mmoL·L-1或高温(45℃或50℃)处理15min可明显抑制胞内核酸酶的活性。

The activity of Spirulina platensis A9 was studied, the results show that Spirulina platensis A9 had very srong intraceUular nuclease activity. Methods for inhibiting the intraceUular nuclease activity were made basically. The intracellular nuclease activity was inhibited obviously when it was cultured with 2.4 mmoL·L^-1EDTA in Zarrouk culture medium or treated for 15 minutes at 45℃ or 50℃.
