Description
Technical field
The invention belongs to microbial fermentation technology field, be specifically related to a kind of natural L-(+)-tartaric fermentation method for producing.
Background technology
L-(+)-tartrate is a kind of natural organic acids, is present in various plants, and as there being high level in the fruit plants such as grape and tamarinds, its of many uses and demand cumulative year after year.In foodstuffs industry, L-(+)-tartrate can be made the first-class of auxiliary and the food dye composition of acidic flavoring agent, swelling agent, antioxidant, and its maximum purposes is drink additive; In pharmaceutical industries, can be used as medical resolving agent; In organic synthesis, can be used for preparing multiple chiral catalyst, or synthesize complicated natural product molecule as chiral source, be very important chiral ligand and chiron; In mirror industry processed, be an important auxiliary agent and reductive agent, can control the formation speed of silver mirror, obtain the coating of homogeneous; In other industry, also can print and dye reserving agent, photographic developer etc.
In early days, L-(+)-tartrate mainly extracts and obtains from by product winestone vinous, but owing to being subject to the restriction of raw material, output cannot satisfy the demands.In recent years, L-(+)-tartaric main production technology was chemical synthesis and half biological synthesis process.Chemical synthesis is owing to producing in process of production a large amount of waste water and the useless non-friendly material of environment that admittedly waits, for later regulation brings many troubles.
Half biological compositional rule mainly utilizes the microorganism with cis-Epoxysuccinic acid hydratase to produce L-(+)-tartrate by enzymatic conversion.At application number, being for example 201010609478.6 discloses a kind of L-(+)-tartaric production method in " a kind of L(+) tartaric production method ", step is: (1) is added to Sodium Hydrogen cis-Epoxysuccinate in the aqueous solution of freezing mother liquor and makes mixing solutions, adjust pH, add red rhodococcus hydrolysis; (2) add calcium sulfate calcification, filter to obtain L (+) calcium tartrate solid and calcification mother liquor, calcification mother liquor is freezing, and centrifugation obtains sal glauberi solid and freezing mother liquor, and freezing mother liquor is back to use step (1); (3) by L-(+)-calcium tartrate solid sulfuric acid solution, filter and obtain L-(+)-aqueous tartaric acid solution, pass through successively positively charged ion, anionite-exchange resin, through concentrated, crystallization, separation and oven dry, obtain L-(+)-tartrate.Calcification mother liquor and calcium sulfate reusable edible that this invention produces in process of production, reduced the problem of environmental pollution, also to a small amount of product L-(+)-calcium tartrate dissolving in calcification mother liquor and not the cis-form epoxy succinic acid sodium of complete reaction reclaim, improved product yield.But in this method, producing the precursor substance cis-form epoxy succinic acid that L-(+)-tartrate uses still needs to adopt chemical method synthetic.
Along with socioeconomic fast development, people's standard of living has obtained significantly improving, and cooking culture is variation day by day, and people improve food safety attention degree, and the wholesomeness of food is paid attention to increasingly.People are more remarkable to the demand of natural foodstuff additive, so the R and D of natural additive for foodstuff are all devoted in current countries in the world.And at present, domestic not yet discovery utilizes biological direct fermentation synthesis of natural L-(+)-tartaric technique.
