FIELD: biotechnology.
SUBSTANCE: method of production of a fermentation product from lignocellulose-containing material. The lignocellulose-containing material is preliminary treated. Then the hydrolysis of preliminary treated material is carried out. After the hydrolysis the fermentation is carried out using the fermenting organism. The fermentation is started and carried out at a concentration of the fermenting organism in a range of 2-90 g of weight of the fermenting organism in a dry state per 1 litre of medium for fermentation. And the fermentation is carried out as feed batch fermentation where C6 and C5 of sugar are fermented simultaneously. Preferably the fermentation product is ethanol.
EFFECT: method enables to increase the yield of ethanol.
