Description
Technical field
The invention belongs to the biological products manufacture field, relate to the method for the glutamine in a kind of four-area simulated moving bed separation and purification fermented liquid.
Background technology
L-glutaminate is a seed amino acid of the γ-Carboxylamideization of L-L-glutamic acid, chemical name 2,5-diamino-5-oxopentanoic acid, constitute one of proteinic primary amino acid as 20 kinds, glutamine is rich in amino acid in the blood of human body, also is rich in amino acid in the Skeletal Muscle Cell, accounts for the over half of whole body total free aminoacids, playing a part very importantly in the organism metabolism, is a kind of " conditionality indispensable amino acid ".After nineteen fifty-two has been determined its molecular structure with the X-ray diffraction, its application is just caused people's attention day by day, one of most important amino acid known to being considered at present also is a kind of extremely rising new drug.Glutamine production is mainly used fermentation method at present, and the fermentative Production glutamine is able to suitability for industrialized production and also depends on the glutamine separation and extraction technology.It is the column chromatography of filler that the separation and Extraction of at present domestic and international glutamine nearly all adopts with ion exchange resin, though can carry out mass preparation, isolating efficient is low, and the moving phase waste is serious, and the stationary phase utilising efficiency is low, yields poorly the cost height.
Since the seventies, American UOP company has developed the chromatographic technique of simulation moving-bed (SMB) principle, this technology is not moving after making the absorbent particles filling, by the method that raw material is imported and exported and product liquid flow inlet and outlet constantly switches, the formation absorbent particles flows relative to countercurrent movement with liquid simulates moving of stationary phase.The nineties in 20th century, the simulated moving bed chromatography range of application also constantly enlarged, spread all over a lot of production fields such as oil, fine chemistry industry, biological fermentation, medicine, food, especially in the separating of mixtures such as homologous compound, chiral isomer medicine, carbohydrate, organic acid and amino acid, demonstrate its special performance.Some patent documentations of the U.S. have reported that simulated moving bed chromatography separating chiral medicine such as optical isomer, racemize material separate with enantiomorph and petroleum chemicals.Japan Daicel chemical industrial company has also developed the method for using simulated moving bed chromatography separating chiral isomer.But, do not see open report yet for the method for using simulated moving bed chromatography to separate the purification glutamine.
Summary of the invention
The objective of the invention is to: provide the method for the glutamine in a kind of four-area simulated moving bed separation and purification fermented liquid, industrialization continuous production, purity, yield and the output of raising product.
Technical solution of the present invention may further comprise the steps: a, glutamine yeast fermentation broth are packed in the ultrafiltration apparatus of PES ultra-filtration membrane, carry out ultrafiltration under the nitrogen of 0.25MPa and remove yeast cell thalline, solid substance and protein being no more than, reduce the viscosity of feed liquid; B, the fermented liquid of ultra filtration is passed through activated carbon decolorizing; C, the fermented liquid after will decolouring are by concentrating under reduced pressure, crystal desalination; D, the coarse-grain after the desalination is made into concentration is that the sample introduction liquid of 10-80g/l is packed into and adsorbed among the simulated moving bed system SMB that Zeo-karb is housed, deionized water by pH10-14 carries out wash-out, control the travelling speed of each functional zone sample, glutamine and L-glutamic acid are collected from extracting solution and raffinate outlet respectively; E, simulation moving-bed extraction liquid are concentrated into anhydrous through Rotary Evaporators, by after the methanol-eluted fractions vacuum drying oven dry finished product.
Simulated moving bed system in the inventive method is by many identical cation exchange resin column series connection, switching in order between i.e. absorption by the strong and weak absorbed component in the ion exchange process, refining, desorb, the resin regeneration difference in functionality district, separate according to the different principle of strong and weak absorbed component travelling speed on separating medium, the position that the switching by combined valve changes opening for feed, raffinate outlet, moving phase inlet, extracting liquid outlet obtains target product; Wherein, the standard of switching time is the travelling speed that the radical of flow velocity by adjusting each functional zone elutriant and ion exchange column comes the controlled target thing; The quantity of each functional zone ion exchange column, is switched by functional zone during switching in this switching time of eluted migration length decision according to the target compound of required wash-out.
Simulated moving bed chromatography in the inventive method (SMBC) separation system is connected to form by wash-out pump, sampling pump, extraction pump, chromatographic column, magnetic valve, signal picker, central controller and computer, wash-out pumping capacity 200-800ml/min, pressure 1-10Mpa; Sampling pump flow 10-50ml/min, pressure 1-10Mpa; Extraction pumping capacity 100-500ml/min, pressure 1-10Mpa; Carry surplus pumping capacity 100-500ml/min, pressure 1-10Mpa; Valve switching time is 18-24min; Whole simulation moving-bed temperature is 25-35 ℃, 25-35 ℃ of feeding liquid, elutriant temperature, and the two temperature is consistent.
Simulated moving bed system in the inventive method is connected by 4-16 radical ion exchange column, simulated moving bed system is according to the Fen Si district, position of four mouths, every district is by the identical ion exchange column of 1-4 root, one district is positioned between elutriant ingress and the extracting liquid outlet place, in this district, realize the desorb of strong absorbed component in the glutamine ferment liquid crude extract; Two districts are positioned between extracting liquid outlet place and the opening for feed, and its effect is equivalent to rectifying tower, make in the glutamine crude extract strong absorbed component absorption repeatedly, desorb and concentrate, and obtain L-glutamic acid from extracting liquid outlet; Three districts are positioned between opening for feed and the raffinate outlet, and its effect is as much as possible glutamine and L-glutamic acid to be adsorbed on the stationary phase, obtain containing glutamine from the raffinate outlet; Four districts are positioned between elutriant inlet and the raffinate outlet, and on the one hand, the glutamine in the liquid phase is fixed with L-glutamic acid and adsorbs mutually, and its elutriant enters a district with fresh elutriant, thereby reaches the purpose of recycle; Jiang San district and one separates out on the other hand, pollutes extracting solution in order to avoid glutamine in the raffinate and L-glutamic acid enter a district, plays certain shock absorption.
Method of the present invention adopts the glutamine in the simulated moving bed system separation and purification fermented liquid, the serialization suitability for industrialized production, and good product purity, efficient height, output is big, production cost is low.
