FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology. Method for producing ethanol is provided, which involves the fermentation of CO-containing gaseous substrates by means of acetogenous bacteria. Method includes obtaining a fermentation medium by mixing liquid media containing a transition metal selected from the group consisting of W, Zn, Co, Ni, with a second liquid medium comprising a transition metal selected from the group consisting of W, Zn, Co, Ni, and optionally a non-metal element Se.
EFFECT: invention provides for the fermentation of CO-containing gaseous substrates with a reduced amount of water and prevention of the deposition of elements in the medium.
