A composition comprising immobilized cells obtained by applying a dispersion of cells and curable prepolymer material selected from the group consisting of polyazetidine prepolymers, carboxymethyl cellulose, polyurethane hydrogel prepolymers and polymethylene isocyanates. as a coating to a solid inert carrier and curing the prepolymer on the carrier at a temperature below the temperature at which enzyme activity of the cells is significantly reduced. The composition may be used to produce various materials such as L-aspartic acid, L-alanine, 6-Aminopenicillanic acid, high fructose corn syrup, prednisolone or phenylalanine.
本发明涉及一种组合物,包括通过将细胞分散液和可固化预聚物材料中的一种或多种,从羧甲基纤维素、聚醚型水凝胶预聚物和聚亚酰胺预聚物中选择的涂层应用到固体惰性载体上并在载体上固化预聚物,从而获得固定化细胞。在细胞酶活性显著降低的温度下,对载体进行预聚物的固化。该组合物可用于生产各种材料,如L-天冬氨酸、L-丙氨酸、6-氨基青霉烷酸、高果糖玉米糖浆、泼尼松龙或苯丙氨酸。
