The results showed that the addition of CTAB enhanced MTG accumulation, and the optimal addition time and concentration of CTAB were 32 h and 1%. The maximum MTG activity in the culture broth was 5.04u/mL and increased by 21.8% compared with the control.

• 结果表明；添加CTAB可以提高发酵过程中谷氨酰胺转胺酶的酶活；摇瓶培养中；CTAB的最佳添加时间和添加量分别为32h和1%25；发酵终了时；谷氨酰胺转胺酶酶活最高达5.；04u/mL；比对照提高了21
