Beschreibung
Zusammenfassung:	The object is to produce an ammonium succinate solution which can be used for the production of fermentation-derived succinic acid, and whose all by-products can be re-used in the production of succinic acid, with a high degree of efficiency and without employing any complicated step. Disclosed is a process for producing a solution of fermentation-derived ammonium succinate, which comprises the following steps (1) to (5): (1) a crystallization/fermentation step for producing calcium succinate trihydrate by using a microorganism; (2) a transfer step for transfering/crystallizing calcium succinate trihydrate to calcium succinate monohydrate; (3) a crystal separation step for separating calcium succinate monohydrate; (4) a salt-substitution step for converting calcium succinate monohydrate separated in the proceeding step to an ammonium succinate solution; and (5) a solid/liquid separation step for removing a calcium carbonate precipitate from the ammonium succinate solution.
