Biotechnological method for producing butanol and butyric acid

摘要

The present invention relates to a method for producing C4 bodies, preferably butyric acid and/or butanol, comprising the steps contacting an aqueous medium comprising an acetogenic bacterial cell in an aqueous medium with syngas and incubating the mixture obtained in step a) at a temperature between 0 and 100° C. for at least 30 minutes, wherein the aqueous medium comprises, in step b), ethanol and/or acetate at a total combined concentration is at least 0.1 gL−1.

1. A method for producing a C4 body, the method comprising:
contacting an acetogenic bacterial cell in an aqueous medium with syngas under anaerobic conditions and optionally in the absence of carbohydrates, thereby obtaining a mixture; and incubating the mixture at a temperature between 0 and 100° C. for at least 30 minutes, wherein in said incubating, the aqueous medium comprises at least one of ethanol and an acetate at a total combined concentration of at least 0.1 g L−1.
