| Abstract: | Continuous fermentation of cheese whey powder(CWP) by immobilized Kluyveromyces marxianus and Saccharomyces cerevisiae to produce fuel ethanol was studied.The results showed that single-column continuous fermentation by mixed strains was better than double-column continuous fermentation(it could shorten fermentation period to 36 h and alcolicity could reach up to 4.7 %vol). |
