PROCESS FOR THE PRODUCTION OF L-ASPARTYL-L-PHENYLALANINE ESTER

摘要

L-Aspartyl-L-phenylalanine R-ester (APR), wherein R-ester is an ester residue of an alcohol of 2 or more carbon atoms or substituted or unsubstituted phenol, is prepared in higher yield than the corresponding methyl ester (APM) by the action of a microorganism or enzymic product thereof on L-aspartic acid and L-phenylalanine R-ester. Certain genera of microorganism are specified and certain species are exemplified.
