Abstract: | Summary Application of an immobilized growing yeast cell system to continuous production of ethanol in high concentration (10%) was investigated using Saccharomyces cerevisiae IFO 2363. When a medium containing 25% glucose was fed, the growth of yeast cells in gel was inhibited. The inhibitory effect was found to be reduced by a stepwise increase in concentration of glucose in the feed medium. The stepwise operation resulted in constant growth of cells in the gel even in the medium containing 25% glucose. By this stepwise feeding system, continuous production of ethanol of 114 mg/ml was maintained at a retention time of 2.6 h for over 2 months and a conversion rate of glucose to ethanol of over 95% of theoretical, was achieved. |
