Methods of biomass processing with the aim of obtaining bioethanol

Research work is devoted to the study of methods of biotransformation of cellulose-containing raw materials in order to obtain bioethanol. Data on environmentally friendly technologies of processing of biomass are presented. Directly, the experimental part of the work presents the results of enzymatic production of monosaccharides, where the substrate was peat of the upper type, with a degree of decomposition of 15%. It is shown that cellulose-containing raw materials are more effective to pretreat 7% H2SO4 120°C for 21 hours. As multienzyme drug was used Agrocel R1000. The following valuable monosaccharides were obtained: D-glucose (3.97%), D-galactose (0.26%), D-rhamnose (0.51%) and D-xylose (1.34%). These products of enzymatic hydrolysis of peat can be successfully used to produce bioethanol, using the process of fermentation thermophilic resistant microorganisms.
