FIELD: chemistry.
SUBSTANCE: method of producing organic solvents involves periodical reduction of pressure in a fermenter during fermentation of carbohydrate-containing material and simultaneous distillation of organic solvents and gases formed during fermentation. Fermentation is carried out on a culture medium using Clostridium acetobutilicum bacteria.
EFFECT: increased output of butanol and allows for varying ratio of desired products during biosynthesis; total output of solvent is 8,5 g/l/day.
