ResultThe maximumabsorption wavelength of reaction solution was about 720nm.The fermentation volume,adding the activated carbonor not,pHvalue of reaction solution and so on had no great effect onthe determinationresults and they could increase the screening efficiency.The effect of ultrasonic treatment for20min was obvious.When50ml volumetric flask was used,the suitable sampling volume was 2.5ml.It was better to centrifugate the fermentationliquid and the supernatant could be taken after standing inthe determination when necessary.

结果反应液最大吸收波长在720nm左右；发酵体积、加入活性碳与否、反应液的pH值等对测定结果影响不大，在筛选时可大大提高效率；超声波处理20min效果明显；在用50ml容量瓶进行定容时，取样体积以2.5ml为宜；对发酵液进行离心效果更好些，但在必要的情况下，可静置后取上清测定。
