A process for producing an optically active aminopolycarboxylic acid, such as S,S-ethylenediamine-N,N'-disuccinic acid, from a mixture of a diamine, such as ethylenediamine, with fumaric acid using a microorganism having a lyase activity, wherein at least one metal ion selected from the group consisting of an alkaline earth metal, iron, zinc, copper, nickel, aluminum, titanium and manganese is added to the reaction system. According to this process, aminopolycarboxylic acids, such as S,S-ethylenediamine-N,N'-disuccinic acid, or metal complexes thereof, can be appropriately and efficiently produced while improving the reaction yield.
一种利用具有裂解酶活性的微生物从二胺(如乙二胺)与富马酸的混合物中生产光学活性氨基多羧酸(如S,S-乙二胺-N,N'-二丁二酸)的工艺,其中在反应体系中加入至少一种选自碱土金属、铁、锌、铜、镍、铝、钛和锰组成的组中的金属离子。根据该工艺,可以适当而有效地生产氨基多羧酸,如 S,S-乙二胺-N,N'-二丁二酸或其金属复合物,同时提高反应产率。
