FIELD: biotechnology, microbiology, biochemistry.
SUBSTANCE: invention relates to the strain Aspergillus oryzae-4150 obtained by selection from the known strain Aspergillus oryzae-387 (VKPM F-683) by multistep selection using effective methods of mutagenesis. The strain is stored as lyophilic dried culture and on slants with wort-agar in section of biotechnology of enzyme preparation, in food processing industry department of the State Scientific Institute of VNII food processing technology in Moscow. Invention provides preparing acid α-amylase showing high activity that exceeds activity in analogue by 2-3 times and reducing the process culturing time.
EFFECT: improved and valuable properties of strain.
