Digestive enzyme preparation like pancreatin and diastase are generally sensitive to gastric juice and their major portion is destroyed on the contact with gastric juice. In oder to obtain acid-stable digestive enzyme, which would fully exhibit its digestive power in gastric juice, approximately 79 strains of Aspergillus sp. were isolated from natureal source, food and crude drugs, sumitted to wheat bran culture, and potency assay was carried out on their culture extract. four of the strains isolated, belonging to Aspergillus sp., had strong proteinolytic activity at pH 3-6.
