The ethanol productivity of immobilized yeast cells varied with monomer composition, and the optimum monomer composition was 20%: 10% of ( HEA-M-23G). Using porous hydrophilic polymer resulted from radiation polymerization at low temperature was effective for immobilization of yeast cells. 固定化酵母的乙醇生产力因单体组成而变化,由20%:10%(HEAM23G)组成的高分子固定化酵母的乙醇生产力最高。
