Целью данной работы было изучение двух типов: физико-химической предварительной обработки щёлочью и кислотой обыкновенного тростника. Предварительная обработка с кислотой обнаружила превосходство над щелочной обработкой по отношению к скорости ферментативного гидролиза и, как следствие, увеличению производительности этанола. В среде предварительной обработки с 6% кислотой в автоклаве показало высокое содержание общего редуцирующего сахара (25,4 г/л). Ферментация гидролизатов тростника с Saccharomyces cerevisiae способствующая выходу продукта в количестве 16,5 г/л этанола. Результаты проведённых исследований показывают, что используемая биомасса крайне актуальна для производства этанола. В этой связи, обыкновенный тростник может быть использован для производства биоэтанола, и становится потенциальным кандидатом для будущего производства по результатам проведённых исследований.</p></abstract><trans-abstract xml:lang="en"><p>The bioconversion of raw materials of ordinary cane into fermented sugars for the production of bioethanol is an urgent and dynamically developing area of research. The purpose of this work was to study two types of physicochemical pretreatment with alkali and acid of ordinary cane. Pretreatment with acid showed superiority over alkaline treatment in relation to the rate of enzymatic hydrolysis and, as a consequence, an increase in ethanol productivity. In a pretreatment medium with 6% acid in an autoclave, a high content of total reducing sugar (25.4 g/l) was shown. Fermentation of cane hydrolysates with Saccharomyces cerevisiae contributing to the yield of the product in the amount of 16.5 g/l of ethanol. The results of the conducted studies show that the biomass used is extremely relevant for the production of ethanol. In this regard, ordinary cane can be used for the production of bioethanol, and becomes a potential candidate for future production based on the results of the conducted research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биоэтанол</kwd><kwd>натрий гидроксид</kwd><kwd>предварительной обработки</kwd><kwd>обыкновенный тростник</kwd><kwd>ферментация</kwd><kwd>гидролиз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bioethanol</kwd><kwd>sodium hydroxide</kwd><kwd>pretreatment</kwd><kwd>common cane</kwd><kwd>fermentation</kwd><kwd>hydrolysis</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">Lakatos G.E., Ranglová K., Manoel J.C., Grivalský T., Kopecký J., Masojídek J.
