Preparation of d-malic acid or derivative |
| abstract |
D-malic acid is produced from D,L-malic acid by subjecting the racemate to the action of a microorganism or product thereof which assimilates L-malic acid but not D-malic acid, until the L-malic acid in the racemate is substantially consumed. D-malic acid recovered from the reaction mixture has a high degree of optical purity. Preferred microorganisms are bacteria such as $i(Pseudomonas putida) and $i(Acinetobacter calcoaceticus). |
