FIELD: biotechnology, microbiology, biochemistry.
SUBSTANCE: invention relates to development of a novel strain used for preparing enzyme representing a complex of acid subacid proteases. Strain is prepared by selection from the known strain Aspergillus oryzae (VKPM F-683) by multistep selection using effective methods of mutagenesis. Strain is stored as lyophilic dried culture and on slants with wort-agar in the biotechnology section of enzyme preparations in the food processing department of the State Scientific Institute VNII of food processing technology in Moscow. Invention provides preparing the strain possessing the high level of synthesis of acid and subacid proteases and high total activity of enzyme in cultural fluid exceeding activity of analogue by 2.0-2.6-fold and in reducing culturing process time.
EFFECT: improved and valuable properties of strain.
