摘　　要：研究了复合载体固定酵母的条件 ,通过正交实验确定了K 卡拉胶 ,魔芋多糖和去离子水用量 .用扫描电子显微镜观察了固定化酵母冷冻前后的形态变化 ,固定化酵母多次使用后 ,其生物合成胞二磷酸胆碱 (CDPC)The conditions of entrapping yeasts by mixed supports, k carrageenan and konjac glucomannan were studied.Through orthogonal experiments,the amount of k carrageenan, konjac glucomannan and deionized water were determined. The shape of immobilized yeasts was observed by scanning electron microscope, which was different between immobilized yeasts and frozen immobilized yeasts.High activity of immobilized yeasts was shown after they were used several times for biosynthesis of CDPC.
