    • The present invention relates to a method of producing [S,S]-ethylenediamine-N,N′-disuccinate wherein a microorganism having malate isomerase activity or matter processed therefrom and a microorganism having ethylenediamine-N,N′-disuccinate ethylenediamine lyase activity or matter processed therefrom are allowed to act on a substrate solution containing maleic acid, maleic anhydride, or a maleic acid salt, and ethylenediamine, in the presence of at least one metal ion selected from the group consisting of alkaline earth metals, iron, zinc, copper, nickel, aluminum, titanium and manganese. The present invention enables to accumulate [S,S]-ethylenediamine-N,N′-disuccinate in a higher yield and at a high concentration within a reaction system using maleic acid as a raw material.
