Study on Whey Fermentation by Mixed Yeast to Produce Fuel Ethanol

Xuewu Guo

Abstract

Whey fermentation by mixed yeast(Kluyveromyces marxianus and Saccharomyces cerevisiae) to produce fuel ethanol was studied.The results showed that the best ratio of the two yeast was 1∶1,and Saccharomyces cerevisiae was added in the fermenting solution 3 h later after the inoculation of Kluyveromyces marxianus,which could shorten fermentation time from 96 h to 72 h.
