PROCESS FOR MANUFACTURING ALCOHOL BY FERMENTATION

摘要

In a process for manufacturing alcohol by fermentation employing immobilized microbial cells, a single fermenter is used for both the immobilization of microbial cells by gellation and the fermentation of yeast in order to avoid contamination by various germs. A second fermenter may be employed for further fermentation of culture liquor from the first fermenter to obtain a high yield of alcohol. The removal of flocs of microorganisms and various germs is also useful for maintaining a high yield of alcohol.
