FIELD: chemistry.SUBSTANCE: invention relates to biotechnology. Disclosed composition for preparation of a product, selected from a group consisting of alcohols, organic acids, sugars, hydrocarbons and mixes thereof. The composition contains cellulosic or lignocellulosic material and cellulolytic enzyme and/or a fermentation-triggering microorganism. According to gel-permeating chromatography results, the cellulosic or lignocellulosic material has a peak of maximum molecular weight of less than 25000 and crystallinity of less than 55%, determined by X-ray diffraction, wherein the material has a bulk density of less than 0.5 g/cm, determined according to ASTM D18 95B.EFFECT: higher fermentation capacity of cellulosic or lignocellulosic material.13 cl, 40 dwg, 9 tbl, 20 ex |
