摘　　要：利用从味精废水中筛选出的一株高活性假丝酵母Ｙ－１０进行味精废水处理．对ｐＨ、温度、接种量、装液量、处理时间等工艺条件进行了研究，确定最佳条件为：ｐＨ５．４，温度３０℃，接种量１０％．在最佳条件下应用新型气升式双向内环流动态反应器培养假丝酵母Ｙ－１０处理味精废水，废水ＣＯＤ去除率达９５．１％，菌体干重达２２．６２ｇ／Ｌ．Monosodium glutamate (MSG) waste water was treated by Candida Y-10 selected from the waster water. The behavior of MSG waste water treatment by Candida Y-10 in different culture conditions was studied and the optimum treatment conditions were obtained: pH=5.4, treatment temperature 30℃ and inoculation rate 10%. A dynamic airlift twodirection loop bioreactor was used to treat MSG waste water under the optimum treatment conditions. The COD was reduced by 95.1% and dry weight was up to 22.62 g/L.
