FIELD: biotechnology, microbiology, biochemistry.
SUBSTANCE: invention relates to the strain Aspergillus oryzae-12 providing the high level of synthesis of acid proteases and xylanase. The strain is obtained by multistep selection of the strain Aspergillus oryzae-387 (VKPM F-683) using effective methods of mutagenesis. The strain is deposited in collection VKPM at № F-932. Invention provides preparing the enzyme complex showing the high proteolytic and xylanolytic activity in cultural fluid wherein their level exceeds activity in analogue by 2.5-2.8-fold.
EFFECT: valuable properties of strain.
