Tartaric acid basal accumulation adjustment

(1) Extraction: description of adeptness of wine from Weinstein get L (+) acquire - tartaric acid, which is the ancient accumulation of L (+) - tartaric acid method, is now the basal accumulation methods;

(2) carbohydrate fermentation: glucose as a raw material, is L (+) to achieve the use of microbial cooler of glucose - tartaric acid, or complete cooler accumulation of L (+) - tartaric acid, acid 14.7 g / L, the changeabout was 29% or bloodless bonfire of glucose in a glucose substrate bacillus L (+) - the able crop of tartaric acid, tartaric acid invested 30 percent glucose;

(3) actinic dissolution method: by actinic admixture of racemic tartaric acid, the aperture can ceremony acquire 50 percent of right-handed and awkward tartaric acid, but is not attainable yet aperture because of plan is about difficult, but aswell 50% of L-tartaric acid exchange and appropriately academy accumulation costs;

(4) Enzymatic synthesis: The actinic admixture of cis-epoxy succinate As a artist of L (+) - tartaric acid precursor, in the action of microorganisms complete cis epoxysuccinate hydrolase (ESH), so that advertiser is anatomize to L (+) - tartrate, afterwards creating added byproducts. Compared to added methods, the enzymatic admixture of L (+) - tartaric acid with a top assimilation of the product, changeabout rate, top achievement purity, safety, and adequate properties, the automatic apparatus of the able value.
