摘要
利用普鲁士蓝悬浮液在波长为690nm处有一最大吸收峰的原理,研究了一种快速测定真菌发酵液中含糖量的新方法.其结果与传统的斐林试剂法完全一致.新方法使用简便、结果准确.采用该法测定样品中的含糖量,可以在短时间内测定大批量的样品.平均回收率为95.6%.灵敏度和精确度均佳于斐林试剂法.这一新方法适用于多种发酵液样品及其他样品的含糖测定.
Based on an absorption peak existed at 690 nm of prussian blue suspension, we studied a new method of measuring sugar content in fungal fermentation suspensions. The results measured by this method are similar to those done by traditional Fehling solution method. The advantages of this new method are simple, accurate, sensitive and reliable. Besides, we can measure many samples at the same time. This method can also apply to other kinds of suspensions.
