После обработки из соломы выделены фракции целлюлозы, гемицеллюлоз и лигнина. Полученные фракции полисахаридов подвергали ферментативному гидролизу с использованием препарата «Целлолюкс-А». С целью оптимизации процесса термообработки методом математического моделирования с использованием программы Design-Expert 8.0.5.2 исследовано изменение массовой доли сахаров ферментолиза фракций полисахаридов соломы в зависимости от технологических факторов термообработки: температуры, продолжительности и мощности облучения. Установлено, температура 103 °C, продолжительность обработки 5 мин и мощность облучения 48,5 Вт являются оптимальными условиями для максимального выхода сахаров. Расхождение между прогнозируемым и экспериментально полученным выходом сахаров составило 1,8%, что подтверждает обоснованность полученной модели.</p></abstract><trans-abstract xml:lang="en"><p>Heat treatment of wheat straw biomass in the environment of 1-butyl-3-methylimidazolium chloride is executed at temperatures of 80, 100, 120 and 140 °C using ultrasonic frequency of 44 kHz and a power of 10, 30 and 50 W. Cellulose, hemicellulose and lignin were isolated from straw after treatment. The resulting fractions of polysaccharides were subjected to enzymatic hydrolysis using preparation Tsellolyuks A. The change of the mass concentration of sugars yielded in the enzymatic conversion of straw polysaccharides depending on the heat treatment process factors (temperature, duration and power) was investigated to optimize the heat treatment process by mathematical modeling using Design-Expert 8.0.5.2 program. The temperature of 103 °C, processing duration of 5 minutes and the power of 48.5 W were found to be optimum conditions for the maximum yield of sugars. The discrepancy between the predicted and experimentally obtained sugar yield was 1.8% that confirms the validity of the received model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>солома</kwd><kwd>полисахариды</kwd><kwd>хлорид 1-бутил-3-метилимидазолия</kwd><kwd>фракционирование</kwd><kwd>ультразвук</kwd><kwd>моделирование</kwd><kwd>оптимизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>straw</kwd><kwd>polysaccharides</kwd><kwd>1-butyl-3-methylimidazolium chloride</kwd><kwd>fractionation</kwd><kwd>ultrasound</kwd><kwd>modeling</kwd><kwd>optimization</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Brandt A., Ray M.
