Reaction Steps
Three samples of disodium cis-epoxysuccinate solution containing different amount of tungstate were separately converted to d-tartrate by treatment with a microbiorganism (FERM-P 2507) which has the ability to convert cis-epoxysuccinate to d-tartrate selectively. Disodium d-tartrate enzymatically prepared was converted to calcium d-tartrate, followed by acid-treatment with sulfuric acid to afford d-tartaric acid. The tungstate contents in the product and the starting material are compared in Table 3.
