Abstract
The increasing shortage of fossil hydrocarbon fuel dictates the need to search for and develop alternative energy sources, including plant biomass. This paper is devoted to the study of the Miscanthus plants biomass potential and the analysis of technologies of its processing into products targeted at bioenergy, chemistry, and microbiology. Miscanthus is a promising renewable raw material to replace wood raw materials for the production of chemical, fuel, energy, and microbiological industries. Miscanthus is characterised by highly productive (up to 40 tons per one hectare of dry matter) C4-photosynthesis. Dry Miscanthus contains 47.1–49.7% carbon, 5.38–5.92% hydrogen, and 41.4–44.6% oxygen. The mineral composition includes K, Cl, N and S, which influence the processes occurring during biomass combustion. The total amount of extractives per dry substance lies in the range of 0.3–2.2 % for different extraction reagents. Miscanthus has optimal properties as an energy source. Miscanthus × giganteus pellets showed the energy value of about 29 kJ/g. For the bioconversion of plants into bioethanol, it is advisable to carry out simultaneous saccharification and fermentation, thus reducing the duration of process steps and energy costs. Miscanthus cellulose is of high quality and can be used for the synthesis of new products. Further research will focus on the selection of rational parameters for processing miscanthus biomass into products with improved physical and chemical characteristics: bioethanol, pellets, industrial cellulose, bacterial cellulose, carbohydrate substrate.

Summary
The task of finding alternative energy sources that are environmentally safe and economically affordable is very urgent. An example is the genus Miscanthus plants, a practically inexhaustible source of renewable raw materials in the field of alternative energy. This is due to the chemical properties of their biomass, and to high growth rates and enormous biological productivity, among other things in a temperate climate, which together make their use in Russia promising [2]. Miscanthus extracts include fatty acids, sterols and other aromatic compounds. The main structures of phenolic compounds and sterols of the bark and core of Miscanthus × giganteus include vanilla acid, para-coumaric acid, vanillin, para-hydroxybenzaldehyde, syringaldehyde, campesterol, stigmasterol, β - sitosterol, stigmast-3,5-diene-7-one, stigmast-4-ene-3one, stigmast-6-ene-3,5-diol, 7-hydroxy-β-sitosterol and 7-oxo-β-citerol [3]
