连续细胞循环——真空发酵生产乙醇研究

Study of Ethanol Fermentation Using Vacuum——Cell Recycle

通过连续细胞循环实现了高菌体浓度发酵 ,常压连续细胞循环发酵生产乙醇产率为 9～ 10g/(h·L) ;通过抽真空消除了乙醇抑制 ,连续细胞循环———真空发酵的乙醇产率达 2 3 0 3g/(h·L)。

High cell densties were achieved using cell recycle.The ethanol productvity of cell recycle fermentation in atmospheric pressure is 10g/L.Boiling away ethanol in vacuum eliminated ethanol inhibition The ethanol productivity of cell recycle fermentation in vacuum is 23.03 g/L.
