| Abstract: | In this paper, various methods of immobilization、Carriers and additives for immobilized Yeast cells were studied in ethanol fermentation from molasses. The result showed that the ethanol productivity of the immobilized cells was higher than dissociate cells. Alginate gel of seaweed was a better carrier, ethanol productivity increased about 8 72% than dissociate cells after 48 h. Furthermore, Al 2O 3 and Bran were used to improve the ethanol productivity, enhance the mechanical structure and the life of the particles. |
