요약

The invention provides processes and methods for utilization of carbon dioxide (CO2) in the fermentation of a gaseous substrate comprising hydrogen (H2) and CO2. In particular, the invention allows for the conversion of at least a portion of the CO2 in the gaseous substrate to one or more products, such as ethanol, acetate, and/or 2,3-butanediol.

대표청구항

A process for improving carbon capture in gas fermentation, the process comprising providing a gaseous substrate comprising CO, H2 and CO2 to a bacterial culture in a liquid nutrient medium and fermenting the culture, wherein at least a portion of the CO2 in the gaseous substrate is converted to one or more products by the culture, the process characterized in that: a. the ratio of H2:CO in the gaseous substrate is at least 5:1; b. the ratio of CO2:CO in the gaseous substrate is between 1:1 and 4:1; c. the amount of CO2 consumed by the culture exceeds or is equal to the amount of CO2 produced by the culture; d. the specific uptake ratio of H2:CO by the culture is at least 1.4:1; and e. the bacteria are carboxydotrophic Clostridium autoethanogenum or Clostridium ljungdahlii.
