FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology. Claimed is a method of obtaining a liquefied biomass, including obtaining the biomass material from sugar beet and/or sugar cane, liquefying the said biomass with enzyme mixture. The said enzyme mixture is used in an amount of at least 0.025% of the biomass. The enzyme mixture includes cellobiohydrolase, beta-glucosidase and polygalacturonase and additionally one or several enzymes with hemicellulase activity, selected from arabinase, xylanase, pectinmethylesterase, ramnogalacturonase and 1,3-/1,6-beta-D-glucanase. Resulting product contains less than 2 wt % of a residual insoluble dry substance.
EFFECT: liquefied biomass is stable in storage and can be used for obtaining products resulting from fermentation, such as ethanol, butanol, acetone, 1,3-propanediol, propanol, acetic acid, lactic acid and propionic acid.
