摘要： The present invention is directed to a process for producing L-aspartyl-L-phenylalanine and/or L-aspartyl-L-phenylalanine diketopiperazine comprising contacting and reacting a culture, cell or a cell-treated product of a microorganism capable of hydrolyzing DKP into AP or capable of performing intramolecular condensation of AP into DKP with DKP and/or AP, in an aqueous medium.
