| 摘要 |
The present invention is directed to a novel, biologically-derived carboxylic acid reductase, also referred to herein as an aryl-aldehyde oxidoreductase, that has been isolated and purified from Nocardia sp. strain NRRL 5646, and to methods of using the carboxylic acid reductase as a biocatalyst for the reduction of carboxylic acids or their derivatives to the corresponding useful product(s). In a preferred embodiment, the invention is directed to biochemically-produced vanillin, and to the methods of its production by the biocatalytic reduction of vanillic acid, or a precursor or derivative thereof, in a reaction comprising the substantially purified, biologically-derived carboxylic acid reductase. |
