FIELD: chemistry.
SUBSTANCE: invention relates to field of biochemistry. Claimed is method for obtaining one or several alcohols from gaseous substrate. Method includes fermentation of gaseous substrate, containing one or more of hydrogen (H2) and carbon monoxide (CO), in water medium in bioreactor, increase of cell density by regulation of hydrogen absorption. Regulation of hydrogen absorption includes determination of hydrogen supply rate, hydrogen discharge rate and regulation of rate of supply of one or more of gaseous substrate and hydrogen. Regulation of hydrogen absorption includes supply of said gaseous substrate in such a way that molar ratio of said hydrogen absorption and rate of gaseous substrate supply is in the first specified interval from 0.001 to 1.0 and in second specified interval from 0.001 to 1.0.
EFFECT: invention provides accelerated increase of cell density in microbiological fermentation of gaseous substrate.
