Description
Technical field
The present invention relates to a kind of device for immobilized enzyme preparation/reaction and application thereof, specifically, relate to a kind of preparation that both can be used for immobilized enzyme, also can be used for device and the embody rule thereof of the enzyme digestion reaction of immobilized enzyme.
Background technology
Enzyme is a kind of biological catalyst produced by the viable cell in organism.Enzyme catalysis have efficient, single-minded, reaction conditions is gentle, the feature such as pollution-free, can under the mild conditions in body, the various biochemical reaction of catalysis expeditiously, promotes the metabolism of organism.Because most of enzyme is protein, very responsive to environment during unbound state, poor at environment stability inferiors such as high temperature, strong acid, highly basic, high ion concentration and part organic solvents, easy sex change, thus its catalytic activity is even lost in reduction, and enzyme can not be reused, after carrying out enzymic catalytic reaction, have residual in product, not easily purifying.Not enough for overcoming these, enzyme immobilization technology arises at the historic moment the sixties in 20th century and progressively grows up.
Body endoenzyme is many to combine with film class material and carries out distinctive catalyzed reaction.Enzyme immobilization technology is the mode of action of analogue body endoenzyme, by means that are chemical or physics, with carrier by enzyme constraint or be limited in certain region, enzyme molecule is made to carry out peculiar and active katalysis in this region, and a kind of technology that is recyclable and that repeatedly use.At present, the Theory and applications research of immobilized enzyme has achieved many important achievement, and is used widely in fields such as food, medicine, chemical industry.Immobilized enzyme is compared with resolvase, both the catalysis characteristics of enzyme had been remained, overcome again the deficiency of resolvase, have that stability strengthens, environmental sensibility reduces, can repeat or use continuously, easily and product separation reduce enzyme auto-degradation, be applicable to the advantages such as multienzymatic reaction.
Crosslinking and entrapping method are enzyme immobilization methods the most conventional at present, two kinds of methods can be used alone, also can conbined usage, improve the immobilization efficiency of immobilized enzyme and the object of Reusability rate to reach, meet actual production or scientific research to the requirement of immobilized enzyme.
Crosslinking refers to by poly functional reagent, the amino-acid residue of resolvase and bifunctional or multi-group crosslink agent be reacted and crosslinked process for fixation occurs.Conventional bifunctional reagent has glutaraldehyde, bis-diazotized benzidine-2-2 '-disulfonic acid etc., and conventional poly functional reagent is the different sulphur cyanogen of Toluene-2,4-diisocyanate-isocyanide-4-, and wherein most widely used is glutaraldehyde.Glutaraldehyde has two aldehyde radicals, all can react with the free amine group of enzyme or protein, forms Schiff, thus makes enzyme molecule crosslinked, make immobilized enzyme.
Entrapping method enzyme is embedded in porous support the method making enzyme fixing, and its preparation technology is easy and condition is comparatively gentle.Carrier does not react with zymoprotein amino-acid residue, seldom changes the higher structure of enzyme, can obtain higher enzymatic activity recovery.Therefore, comparatively speaking, the immobilized enzyme adopting entrapping method to prepare has larger advantage.But because entrapping method prepares the conventional carrier of immobilized enzyme as gelatin, agar, agarose, chitosan, sodium alginate etc., all have full-bodied characteristic, shaping therefore in preparation process has just become a very large technical problem.In prior art, the preparation of immobilized enzyme gel particle generally adopts glass syringe method, that is: draw immobilized enzyme coagulant liquid with syringe, dropwise instill method shaping in forming agent.Actual preparation too much becomes the bottleneck affecting production efficiency because moulding process is consuming time often, so that cannot realize large-scale industrial production.
Due to the plurality of advantages of enzymic catalytic reaction, in recent years, the research of this respect obtains the features such as the enzyme digestion reaction of deep carrying out, particularly diphasic system is fast with speed of reaction, productive rate is high, by product is few and receives much concern.In the enzyme-catalyzed reaction that diphasic system carries out, while reaction, product is enriched to organic phase from aqueous phase, eliminates the restraining effect of product to catalyzed reaction, reduces the generation of by product simultaneously.But due to enzyme easy in inactivation in organic solvent, so often react with the form of immobilized enzyme.Enzyme digestion reaction need operate with special sealed reaction device, and market existing enzyme digestion reaction device is expensive, and can only carry out single enzyme digestion reaction operation, and can not be used for the production of immobilized enzyme, plant factor is not high.

Preferably, the bottom in withstand voltage tank body 1 is placed with screening plant (such as screen cloth), to sieve out immobilized enzyme particle, after question response liquid is released completely, can open flange lid 2, be taken out by screen cloth, obtain collected immobilized enzyme.
Embodiment 4: application apparatus of the present invention carry out the reaction of diphasic system immobilized enzyme hydrolysis
A) by opening for feed 3, the Acetic acid-sodium acetate damping fluid of immobilized enzyme, jasminoidin, pH=3.5 ~ 5.5 and ethyl acetate are pressed proportioning (10: 1: 100: 100, weight ratio) drop in withstand voltage tank body 1, confined reaction system, open whipping appts 7 and well heater, stir at 45 ~ 65 DEG C and make to carry out enzyme digestion reaction;
B) question response terminates, and opens opening for feed and makes reaction system be in atmospheric pressure state, then open valve B12, releases reaction solution.
Preferably, the bottom in withstand voltage tank body 1 is placed with screening plant (such as screen cloth), to sieve out immobilized enzyme particle, after question response liquid is released completely, can open flange lid 2, be taken out by screen cloth, obtain collected immobilized enzyme.
Embodiment 5: application apparatus of the present invention carry out the reaction of diphasic system immobilized enzyme hydrolysis
A) by opening for feed 3, the Acetic acid-sodium acetate damping fluid of immobilized enzyme, baicalin, pH=4.0 ~ 6.0 and chloroform are pressed proportioning (20: 1: 500: 500, weight ratio) drop in withstand voltage tank body 1, confined reaction system, open whipping appts 7 and well heater, stir at 40 ~ 60 DEG C and make to carry out enzyme digestion reaction;
B) question response terminates, and opens opening for feed and makes reaction system be in atmospheric pressure state, then open valve B12, releases reaction solution.
Preferably, the bottom in withstand voltage tank body 1 is placed with screening plant (such as screen cloth), to sieve out immobilized enzyme particle, after question response liquid is released completely, can open flange lid 2, be taken out by screen cloth, obtain collected immobilized enzyme.
Finally be necessary described herein:
The further description that above-described embodiment is only done for the technical scheme proposed the present invention, only understanding technical scheme of the present invention for helping, can not be interpreted as limiting the scope of the invention.The non-intrinsically safe that those skilled in the art's foregoing according to the present invention is made improves and adjustment all belongs to the scope of protection of present invention.
