FIELD: biotechnology. n SUBSTANCE: method for obtaining of C4-substances, in particular, butyric acid, butanol and derivatives thereof, and ethanol and/or acetate application in the inventive method are proposed. The method comprises the step of contacting the aqueous medium containing acetogenic bacterial cell from the group, consisting, in particular, of Clostridium, Moorella, and Carboxythermus, with synthesis gas under anaerobic conditions and at a temperature from 30 to 40°C. Ethanol and/or acetate application results in increased yield of the target product. n EFFECT: desired product obtaining from the synthesis gas in the absence of carbohydrates. n 14 cl, 4 dwg, 3 ex |
