| 摘 要： | 本文研究了海藻酸盐凝胶固定化大肠杆菌细胞的稳定性;珠型凝胶珠的机械强度;多价离子类型及浓度对形成凝胶珠的影响;及用各种不同离子成形的细胞凝胶珠对溶液中磷酸盐的敏感程度.结果表明,海藻酸盐包埋细胞成形的凝胶珠的机械强度、理化及生物学性质皆取决于包埋细胞时海藻酸盐浓度、细胞浓度、使凝胶成形的离子类型及浓度,保存与使用时溶液的 pH 及磷酸盐浓度等综合因素.

| Abstract: | Stability of Alginate-immobilized E.coli cells was studied.Investigations include:mechanical strength of beads,effect of cation type and concentration on beads formation,and susceptibility of alginate beads to phosphate chelation and others.It was found that the physical and chemical beads characteristics depend on a complex interaction of cation type and concentration and pH of phosphate chelation when beads were used and stored.The characteristic also dependon on concentration of alginate and cells when cells were entrapped. |
