摘　　要：固定化酵母的双底物乙醇连续发酵邓旭，郑重鸣，岑沛霖，谢熠（浙江大学化工系二次资源实验室，杭州３１００２７）关键词：固定化酵母，酒精，发酵１前言固定化细胞发酵有着许多游离细胞发酵所不能比拟的优点，如减少细胞流失、增大菌体对外部条件如温度和ｐＨ值的抵抗能...In this paper, the ethanol continuous fermentation processes with glucose, xylose and the mixture of them were studied by using immobilized S.cerevisiae and P. stipitis CBS5773 sepa-rately. The effects of dilution rate, original glucose concentration and the adding of xylosewere evaluated during the process with immobilized S. cerevisiae; the effects of aeration rateand ethanol in culture were also studied in the xvlose fermentation with immobilized P. stipi-tis.The study gave the experimental foundation for the co-fermentation with these two immo-bilized yeasts.
