Abstract

The present invention relates to a method for producing D-pantothenic alcohol by the reaction of D- Pantolactone which is prepared from the microbe enzymatic hydrolysis, and beta-aminopropyl alcohol. In the method, microbe strain fusarium moniliforme fungi SW-902 (i.e. CGMCCNO. 0536) of high yield D-lactone valerate hydrolase which is sieved and conserved are used for fermenting to produce enzymes; the enzymes are used for the hydrolysis of DL-lactone valerate, and the pure D-lactone valerate which is obtained after the lactonization of D-pantoic acid in enzymatic conversion liquor and the beta-aminopropyl alcohol react to produce the D-pantothenic alcohol. A main mass index [alpha][D]<20> is equal to +29.0DEG C to plus 31.5 DEG C.

Description

Microbial enzyme method prepares the method for D-panthenol
Technical field
The present invention relates to the method that microbial enzyme method prepares D-panthenol, relate in particular to and utilize beading Fusarium (Fusarium moniliforme) SW-902 CGMCC No.0536 enzymatic production and carry out enzymic hydrolysis fractionation manufacturing D-pantoyl lactone, react the method for producing D-panthenol with the beta-amino propyl alcohol again.
Background technology
D-pantothenic acid claims pantothenic acid, vitamins B again 5Or B 3, be a kind of important medicine, foodstuff additive and fodder additives.The mankind and animal have physiological demand to D-pantothenic acid; and D-pantothenic acid is extremely unstable; its commercial form is the D-calcium pantothenate; but the D-calcium pantothenate is a solid; range of application is restricted; and D-panthenol; claim pro-vitamin B5 again; be the same effect thing of the D-calcium pantothenate that exists with liquid form, can remedy the deficiency of the Application Areas of D-calcium pantothenate, D-panthenol enters in the human body can be converted into pantothenic acid; and then synthetic coenzyme A; promote human body protein; fat; the metabolism of carbohydrate, the mucous membrane and the hair luster of protection skin surface, the generation that wards off disease; therefore; D-panthenol is specially adapted to medicine as nutritional supplement; food; cosmetic industry is as oral liquid; collyrium; compound VB injection; shampoo; mousse; skin cream etc.
D-panthenol (pro-vitamin B5) is again important makeup and medicinal raw material, and market is in short supply.The production of D-panthenol can not be adopted calcium salt induced crystallization method, and the intermediate pantoyl lactone of synthetic D-panthenol requires to have higher optical purity.
The D-panthenol product of existing market supply all adopts chemical method to split the preparation of D-pantoyl lactone.Chemical method prepares pantoyl lactone and splits with resolving agents such as Chiral Amine, quinine, brucine and the mould ammonia of chlorine, its maximum problem is that operation steps is many, the product purification trouble might have in the product impurity such as the healthy disadvantageous chemical agent of humans and animals, solvents.Also have the resolving agent rate of recovery low, caused a large amount of resolving agents, for example the mould ammonia of chlorine enters waste water, makes that the mould ammonia of chlorine has accounted for 70%~80% of waste water total amount in the waste water, causes that wastewater treatment capacity is big, easily causes environmental pollution.
Though Japan first drugmaker produces the D-pantoyl lactone and adopted the microbial enzyme working system, do not see the report of relevant its synthetic D-panthenol.
Summary of the invention
Purpose of the present invention provides a kind of method that directly prepares D-panthenol with microbial enzyme method, promptly utilize the microorganism strains of high-yield D-pantolactone hydrolytic enzyme, enzyme process splits the DL-pantoyl lactone, the optical purity of D-pantoyl lactone reaches more than the 99%e.e. in the resulting enzymic hydrolysate, reacts the method for producing the high-optical-purity D-panthenol with the beta-amino propyl alcohol again.
A kind of method of microbial enzyme manufactured D-panthenol, comprise and utilize beading Fusarium (Fusariummoniliforme) SW-902 CGMCC No.0536, enzyme process splits the DL-pantoyl lactone, and resulting enzymic hydrolysate D-pantoyl lactone is produced the high-optical-purity D-panthenol with the reaction of beta-amino propyl alcohol again; Described enzymic hydrolysate and beta-amino propyl alcohol with etc. volumetric molar concentration react; 20~80 ℃ of described temperature of reaction, 2~40 hours reaction times.
Description of drawings
Accompanying drawing 1 is a process flow diagram of the present invention.
The present invention realizes by following scheme:
(1) the present invention adopts microorganism strains beading Fusarium (Fusarium moniliforme) the SW-902 CGMCC No.0536 (this bacterial strain has been kept at Zhong Guan-cun, BeiJing, China China Committee for Culture Collection of Microorganisms common micro-organisms preservation center February 12 calendar year 2001) of high-yield D-pantolactone hydrolytic enzyme, enzymatic production, DL-pantoyl lactone with chemosynthesis, refining back is as the enzymatic conversion substrate, enzymatic conversion generates the D-pantoic acid, through lactonizing, the D-pantoyl lactone is made in solvent extraction, decolouring, concentrated, crystallization;
(2) with D-pantoyl lactone and beta-amino propyl alcohol with etc. volumetric molar concentration under certain solvent and 20~80 ℃ of temperature condition, reacted 2~40 hours, through separating, purifying, obtain the D-panthenol of high-optical-purity.
The method of microbial enzyme hydrolysis manufacturing D-pantoyl lactone that the present invention adopts and beta-amino propyl alcohol reaction production D-panthenol has overcome induced crystallization method fractionation DL-calcium pantothenate can not be used for the shortcoming that D-panthenol is produced, it is expensive to have overcome the chemical resolution method resolving agent, the cost height, separation difficulty has problems such as pollution and toxicity.Advantage of the present invention is advantages such as cost is low, technology is simple and easy to control, reaction conditions is gentle, the product safety quality is good, environmental sound.
