Reaction Steps

Still alternatively, both an immobilized biocatalyst with immobilized cells containing maleate isomerase and an immobilized catalyst with immobilized cells containing aspartase are combined and packed into a column and an aqueous solution of maleic acid and ammonia or an aqueous solution of ammonium maleate is passed through the column, to produce L-aspartic acid by a single-step process from maleic acid.
