爭光固定化酶載體Zhengguang immobilized enzyme carrier
固定化酶又稱固相酶,是20世紀60年代伴隨著酶工程研究發(fā)展起來的一種酶應(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)化和自動化等優(yōu)點。時至今日,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、精細化工、檢測分析等領(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,常見的有天然高分子材料、合成高分子材料、多孔無機材料等。酶的固定化對載體材料的粒度、孔結(jié)構(gòu)、結(jié)合位點和形式、機械強度、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.
