| 摘 要： | 本文测定了一株钝齿棒杆菌（Corynebacterium crenatum）诱变菌和二株基因工程菌发酵过程中产arginine曲线、生长曲线以及发酵液中碳源消耗量和pH值的变化。实验结果显示Arg产量最高的菌株为C．crenatumA．S．M2.sp，其产量达到9mg／ml，据此认为钝齿棒杆菌中的argR基因可能为Arg代谢中的一个正调控因子。 |

| Abstract: | In this paper, the growth curve and utility rate of carbon, the pruducing curve of arginine and the pH of the culture medium of C.crenatum were determined. The results showed that C.crenatumA.S.M2.sp is the bacterium which has the highest yield of arginene. The yield of this bacterium gets to 9mg/ml. In conclusion, argR gene of C.crenatum is a positive regulator in the metabolism of arginine. |
