AB - The article presents the characteristics of the chemical composition of the biomass of genus Miscanthus plants and the features of its use for the production of carbohydrate-containing substrates for biotechnology. It is shown that the Chinese mycanthus “Ferner Osten” is not characterized by a high content of lipidic and protein compounds. The herbaceous plant is rich in cellulose, lignin and fiber. To achieve the maximum conversion of the miscantus biomass, a preliminary chemical treatment with dilute sulfuric acid was performed. The optimal temperature for pretreatment of miscanthus biomass with 1% sulfuric acid solution is 130 °C with a process duration of 30 minutes. With an increase in temperature exposure, the yield of cellulose decreases markedly. Thus, when the temperature rises to 140°C and the process lasts 30 minutes, the pulp yield decreases by 31.38 %. With an increase in the duration of chemical treatment from 30 to 60 minutes, the pulp yield decreases from 79.07% to 61.08%. The residues of oligosaccharides and lignin were determined in the chemical hydrolysates of Miscanthus sinensis “Ferner Osten”. Among monosaccharides, glucose and xylose predominate, 40.5 and 24.4% of the dry matter, respectively. To increase the yield of sugars, it is planned to carry out two-stage processing.
