固定化酶又稱(chēng)固相酶，是20世紀(jì)60年代伴隨著酶工程研究發(fā)展起來(lái)的一種酶應(yīng)用新技術(shù)，是將可溶性的生物酶用物理或化學(xué)方法束縛或限制于固體材料上，使之成為不可溶但仍具有其專(zhuān)屬酶活性的狀態(tài)，用于溶液中的各種酶催化反應(yīng)。

       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.

       與游離酶相比，固定化酶具有穩(wěn)定性高、易分離回收、可重復(fù)使用、便于生產(chǎn)連續(xù)化和自動(dòng)化等優(yōu)點(diǎn)。時(shí)至今日，固定化酶技術(shù)已規(guī)模應(yīng)用于食品、醫(yī)藥、農(nóng)業(yè)、環(huán)保、紡織、照相、能源、材料、精細(xì)化工、檢測(cè)分析等領(lǐng)域，極大拓展了酶的工業(yè)化應(yīng)用，潛力巨大，發(fā)展前景十分廣闊。

       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.

       有多種固體材料可作為載體用于酶的固定化，常見(jiàn)的有天然高分子材料、合成高分子材料、多孔無(wú)機(jī)材料等。酶的固定化對(duì)載體材料的粒度、孔結(jié)構(gòu)、結(jié)合位點(diǎn)和形式、機(jī)械強(qiáng)度、熱穩(wěn)定性、化學(xué)穩(wěn)定性、生物親和性和相容性等有很高的要求且不同酶存在差異性，載體材料的結(jié)構(gòu)和性質(zhì)直接決定著固定化酶性能的發(fā)揮。

       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.

       浙江爭(zhēng)光現(xiàn)有多種骨架、孔結(jié)構(gòu)和結(jié)合基團(tuán)的類(lèi)型較為齊全的系列固定化酶載體，固定化酶載體分環(huán)氧、羥基、氨基、疏水、吸附和親和六大類(lèi)，浙江爭(zhēng)光提供的產(chǎn)品具有粒度均勻、結(jié)構(gòu)可控、載酶活力高、批次穩(wěn)定性好、機(jī)械強(qiáng)度優(yōu)等特點(diǎn)，可固載多種生物酶，以滿足不同行業(yè)領(lǐng)域、不同使用環(huán)境下的生產(chǎn)應(yīng)用和科學(xué)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.
