摘　　要：以琼脂、明胶、海藻酸钙、聚乙烯醇和丙烯酰铵凝胶为固定化细胞的包埋固定载体,对其主要包埋条件和性能进行了初步的研究比较。其结果表明,海藻酸钙和聚乙烯醇与琼脂、明胶和丙烯酰胺凝胶相比较,具机械强度较高、传质性能较好,生物毒性较低和固定操作容易等优点,为较好的固定化细胞载体,值得进一步深入研究。Entrapping methods with agar, gelatine, calcium alginate, polyviayl alcohol and acrylamide gels as entrapping agents for immobilizing microbial cell were studied. By comparing their characteristics, calcium alginate and polyvinyl alcohol gels were found to be tie most suitable entrapping agents for their high mechanical stability, good mass dif-fusivity, less toxicity and easiness in entrapping operation.
