Abstract: | オhe combination of ethanol fermentation and solvent extraction is one of effective methods for increasing ethanol production rate.In this paper,extractive fermentation for ethanol production was carried out by using immobilized yeast cell,where the dodecanol was used as extractive solvent.The effects of extractive content,rotary rate and substrate concentration on extractive fermentation have been discussed,the partition coefficient of ethanol in extraction was also examined.They would be useful for further researches on extractive fermentation. |

Keywords: | ethanol fermentation immobilized yeast cell solvent extraction |
