The double enzyme coupling preparation of above-mentioned ornithine hydrochloride, as preferably, in the described steps A, the conversion fluid concentration of substrate is controlled at 50～300g/L.The control decision reaction substrate of concentration of substrate is to the transformation efficiency of target product, and meet the requirement of postorder complete processing, therefore effectively control the concentration of reaction substrate, not only can improve the reaction transformation efficiency, easily can utilize enzyme activity fully, make reaction environment meet the requirement of reaction kinetics, thereby reach stabilization process, enhance productivity the purpose of save energy.
The double enzyme coupling preparation of above-mentioned ornithine hydrochloride, as preferably, in the described steps A, catalyst is Mn
2+Ion, Mn
2+Ionic concn is controlled at 0.2～0.6mmol/L.Mn
2+Catalyst can be: manganous sulfate, manganese acetate, Manganous chloride tetrahydrate etc.
Mn
2+The release of living of the concentration decision enzyme in reaction system, and reaction is to the transfer of product direction, concentration is low excessively, too high all can live by inhibitory enzyme, impels the prolongation in reaction times.
The double enzyme coupling preparation of above-mentioned ornithine hydrochloride, as preferably, among the described step B, the agent of some plate development is n-propyl alcohol and ammoniacal liquor, its mass percent is a n-propyl alcohol: ammoniacal liquor=65～75: 35～25.The mass percent of above-mentioned solution is the mass percent of effective constituent.
The decision of the selection of developping agent and proportioning is to the dissolving of composition and the separating effect between the component, and and between component do not react, and the component of this developping agent is selected and proportioning can make other related impuritieses of product and substrate effectively separate, and presents independent clearly spot.
The most preferred, the mass percent of described n-propyl alcohol and ammoniacal liquor is a n-propyl alcohol: ammoniacal liquor=72: 28.
The double enzyme coupling preparation of above-mentioned ornithine hydrochloride, as preferably, among the described step C, the ornithine hydrochloride crude product is dissolved in the deionized water by weight 10%～30% concentration.
This step is a treating process, and in the production process, disposable products come out to be difficult to directly to reach qualified, therefore needs a treating process.
The double enzyme coupling preparation of above-mentioned ornithine hydrochloride, as preferably, in the described steps A, the preparation method of beef liver enzyme liquid is: get that fresh beef liver is pulverized in freezing pulverizer, cell wall breaking, stand-by 4 ℃ of preservations then, the beef liver slurry is dissolved in the deionized water of 1～4 times of mass ratio, adds Mn
2+Ion, and concentration is controlled at 0.2～0.6mmol/L, heat be incubated 0.5～2 hour between 30～70 ℃ altogether, filters, collection filtrate, and filtrate is deposited in 4 ℃ of refrigerators stand-by behind high speed centrifugation immediately.Mn
