ABSTRACT:
A process for preparing L-aspartic acid by contacting fumarate ion-containing solution with aspartase or aspartase-producing microorganisms, adding maleic acid to insolubilize or precipitate the L-aspartic acid, isomerizing maleic acid in the supernatant liquid to form fumaric acid and recycling the fumaric acid into contact with the enzyme or microorganisms.
