The yeast cells of Kluyveromyces marxianus immobilized on Nypa fruticans leaf sheath pieces was tested for acetic acid tolerance during ethanol fermentation. Control sample with the free yeast cells were also performed under the same conditions. When the acetic acid content in the medium varied from 0 to 8g/L, the cell growth rate of the immobilized and free yeast decreased by 8.3 to 10.3 time, respectively. In addition, increase in acetic acid content from 0 to 8g/L reduced ethanol formation rate of the immobilized and free yeast by 4.1 to 6.8 times, respectively. The immobilized yeast always demonstrated faster sugar assimilation and higher final ethanol concentration than the free yeast. Under acetic acid stress, the fixed yeast exhibited less change in unsaturated degree of fatty acids in cellular membrane than the free yeast. Application of immobilized yeast was therefore potential for improvement in ethanol fermentation from lignocellulosic material.

In order to meet the needs of industrial mass production,people began to explore the effect on different modes to ethanol fermentation.Ethanol fermentation with energy beet was done by using batch fermentation and continuous fermentation.Results showed that batch fermentation was better than continuous mode,but its technology was cockamamie.The residual glucose content in fermenting mash was high when fermentation was continuous.And the fermentation was halfway.But continuous fermentation was convenient for industrialization producing.Although the residual glucose content in continuous fermentation mode was high through 0.06 h-1 sugar concentration,the last translation rate of ethanol was high.
