Open the CIPO recordAbstract From the Canadian patent
Enzyme-catalyzed synthetic reactions having otherwise unfavorable equilibria are facilitated by recovery of product by electrodialysis. Methods and apparatus are provided that can be operated continuously to produce high yields of enriched product without recourse to post-synthetic product manipulations heretofore employed that are expensive and present a risk of residual toxic by-products. The invention is applied to advantage in the preparation of alpha-L-aspartyl-L-phenylalanine lower alkyl esters. 2543Y
