摘要: The present invention relates to specific Escherichia. coli mutants which can be used for the synthesis of D-amino acids, and to such a process. The mutants are distinguished by deficiencies in particular enzymes which break down D-amino acids and include those which produce D-amino acids via the carbamoylase/hydantoinase route.
