Abstract
The invention relates to a method for producing a low-molecular-weight organic compound, such as acetone, butanol, and ethanol, in a fermentation process. The method contains a step of introducing a gas flow into an aqueous solution containing microorganisms producing the low-molecular-weight organic compound; a step of recovering the gas flow through a compound comprising isophoron; and optionally a step of separating the low-molecular-weight organic compound from the composition comprising isophoron.
Claims16
A method for producing a low-molecular-weight organic compound, the method comprising
- A) introducing at least one gas or gas mixture into an aqueous solution comprising microorganisms producing the low-molecular-weight organic compound, which is acetone, butanol, or ethanol,
- B) channeling the gas or gas mixture out through a composition comprising isophorone, and optionally
- C) separating the low-molecular-weight organic compound from the composition comprising isophorone.
