FIELD: chemistry.
SUBSTANCE: invention relates to biochemical industry. Method includes crushing lignocellulosic feedstock in two stages: at first stage to particle size not larger than 20×20×5 mm, at second stage to particle size not larger than 50 mcm, mixing crushed raw material with water with obtaining batch and continuous processing of batch with ultrasound. After that, mesophilic enzyme preparations, containing cellulose, β-glucanase, xylanase, cellobiase, are introduced, and saccharification, fermentation and separation of alcohol from wort by wort-rectification is performed.
EFFECT: alcohol production.
