中文摘要：

在未经灭菌的Zarrouk培养基中分别添加不同浓度的谷氨酸钠和葡萄糖，考察其对螺旋藻生长的影响。结果表明：葡萄糖的最佳添加浓度为3g／L，螺旋藻中的叶绿素含量和藻胆蛋白含量分别是对照的1．9倍和1．13倍；在3g／L葡萄糖浓度下，考察不同浓度的谷氨酸钠对螺旋藻混合营养培养的影响，以干重、叶绿素及藻胆蛋白含量、藻液的污染程度为主要指标，得出1．2g／L为最佳添加量。

英文摘要：

The effects of sodium glutamine with different concentrations on mixotrophic culture of S. platensis were studied. The results showed that when 3 g/L glucose is appended, the content of chlorophyll is 1.9 times of that in control, but the content of phycobiliprotein is only 1.13 times. At the fixed concentration of 3 g/L glucose, among the sodium glutamine concentrations 0, 0.2, 0.6, 0.9, 1.2, 1.5 and 2 g/L, 1.2 g/L is the best, according to the standards of the cell dry weight, the contents of chlorophyll and phycobiliprotein, pollution level of S. platensis.
