    Abstract: Aqueous alpha-amylase preparations may be purified by removing the polyvalent anions therefrom, and contacting the preparations with a fibrous alumina of the kind described in U.S. Pat. No. 2,915,475. The alpha-amylase will be adsorbed on the alumina and may subsequently be recovered therefrom by washing the same with a salt solution containing polyvalent anions. In the case where the alpha-amylase preparation is derived from fermentation of B. subtilis, protease is present in large quantities and when such a preparation is contacted with fibrous alumina the protease will remain in the effluent and can be recovered therefrom by wellknown methods.
