摘    要:制备了一种重化固定化酵母颗粒,可有效防止发酵过程中固定化颗粒上浮,用于气升式内环流反应器,可与器内流体形成良好循环。同时在气升式内环流反应器内对固定化酵母乙醇连续发酵过程进行了研究,得到发酵最优控制条件。通过与其它发酵器对比发现,内环流反应器用于固定化酵母乙醇发酵过程,可大大提高乙醇产率。

关 键 词:乙醇发酵  固定化酵母  环流反应器

Study on Continuos Ethanol Fermentation Using Immobilized Yeast Cells in Loop Reactor
Abstract:オeighting immobilized cells particle was made herein.By using weighting beads,the floating of beads during fermentation could be prevented,and a good circulation of bead substrate was found in loop reactor.Continuos ethanol fermentation using immobilized cells has been also studied in air lift loop reactor.It is shown that the finest operation parameters are: So=180g/L,F=30mL/h,P=17.10mg/(g·h),the utilization of glucose is more than 90%.Compared with the other fermentor,it is found that ethanol production rate can be improved in air lift loop reactor.
Keywords:ethanol fermentation  immobilized yeast cells  loop reactor
