摘要

低温（—78℃）下辐射聚合亲水性单体羟乙基丙烯酸酯（HEA）和疏水性单体甲基丙烯酸缩水甘油酯（GMA）的混合物，用该聚合物poly（HEA-GMA）固定化酵母细胞。固定化酵母具有比游离细胞高的生产乙醇能力，但它们的生产乙醇能力随共聚物的组成而变化，其中用17%：6%（HEA:GMA）聚合的poly（HEA-GMA）固定化酵母的生产乙醇能力最高，为29 mg/ml•h，是游离细胞的4倍。当单体浓度为20%—30%时，poly（HEA-GMA）能获得高活性的固定化酵母。还研究了poly（HEA-GMA）的物理性质同固定化酵母活性的关系。

Abstract

The immobilization of yeast cells was carried out by using the copolymer produced by radiation polymerization of hydroxyethyl acrylate (HEA) and glyciolyl methacrylate (GMA) monomer at - 78℃ low temperature. The immobilized cells with the copolymer, poly (HEA-GMA) had higher ethanol productivity than free cells. However, the ethanol praductivity of immobilized cells varied with the composition of copolymer, in which the ethanol productivity of immobilized yeast cells with the copolymer from 17% HEA and 6% GMA was the highest, 29 mg/ml•h, increasing by 3 times in comparison with that of free cells. And it was obvious that the activity of immobilized yeast cells was higer when the concentration of monomer was 20%—30%. In this work, the relation between the properties of copolymer and the ethanol productivity of immobilized yeast cells was also investigated.
