ABSTRACT:
Aspergillus niger acid protease is prepared by treating whole glucoamylase product containing a mixture of acid protease and glucoamylase with an anion exchange medium which selectively removes acid protease from the glucoamylase, producing a glucoamylase product which is protease-free. The acid protease is then recovered from the anion exchange medium by elution with high salt or low pH solution.
