                         固定化酶又称固相酶,是20世纪60年代伴随着酶工程研究发展起来的一种酶应用新技术,是将可溶性的生物酶用物理或化学方法束缚或限制于固体材料上,使之成为不可溶但仍具有其专属酶活性的状态,用于溶液中的各种酶催化反应。

                         Immobilized enzyme is also called the solid-phase enzyme,with the development of enzyme engineering in 1960s, which is a newtechnology of enzyme application. It is to bind or restrict soluble enzyme tosolid material by physical or chemical methods ,so that it becomes insoluble but still has itsexclusive enzyme activity, which is used for various enzyme catalytic reactionsin solution.

                         与游离酶相比,固定化酶具有稳定性高、易分离回收、可重复使用、便于生产连续化和自动化等优点。时至今日,固定化酶技术已规模应用于食品、医药、农业、环保、纺织、照相、能源、材料、精细化工、检测分析等领域,极大拓展了酶的工业化应用,潜力巨大,发展前景十分广阔。

                         Compared with the free enzyme, the immobilized enzyme has the advantagesof high stability, easy separation and recovery, reusable use, and easyproduction continuity and automation. Up to now, immobilized enzyme technologyhas been widely used in food, medicine, agriculture, environmental protection,textile, photography, energy, materials, fine chemical industry, detection andanalysis and other fields, greatly expanding the industrial application ofenzymes, with great potential and broad development prospects.

                         有多种固体材料可作为载体用于酶的固定化,常见的有天然高分子材料、合成高分子材料、多孔无机材料等。酶的固定化对载体材料的粒度、孔结构、结合位点和形式、机械强度、热稳定性、化学稳定性、生物亲和性和相容性等有很高的要求且不同酶存在差异性,载体材料的结构和性质直接决定着固定化酶性能的发挥。

                         There are many kinds of solid materials that can be used as carriers forimmobilization of enzymes, the common ones are natural polymer materials,synthetic polymer materials, porous inorganic materials, etc. Enzyme immobilizationhas high requirements on the particle size, pore structure, binding site andform, mechanical strength, thermal stability, chemical stability, biologicalaffinity and compatibility of the carrier material, and there are differencesamong different enzymes. The structure and properties of the carrier materialdirectly determine the performance of the immobilized enzyme.

                         浙江争光现有多种骨架、孔结构和结合基团的类型较为齐全的系列固定化酶载体,固定化酶载体分环氧、羟基、氨基、疏水、吸附和亲和六大类,浙江争光提供的产品具有粒度均匀、结构可控、载酶活力高、批次稳定性好、机械强度优等特点,可固载多种生物酶,以满足不同行业领域、不同使用环境下的生产应用和科学研究等的固定化需求。

                         Zhejiang Zhengguang has a relatively complete range of immobilized enzyme carriers with a variety of skeletons, pore structures and binding groups.
