Embodiment 1

[0171] Example 1: Batch fermentation in CSTR

[0172] Aseptically and anaerobically transfer the liquid culture medium (800 mL) containing solution A into a 1 L CSTR container and continuously wash with N 2 purge. Once transferred, the reduced pressure state and pH of the medium can be measured directly by the probe. The medium was heated to 37°C and stirred at 400 rpm. Phosphoric acid (30 mM), sodium tungstate (10 μM), solution B and solution C were then added. Sodium sulfide solution (0.5 mM) was added to the fermentation vessel, and the medium was then depressurized to 200 mV by adding chromium(II) chloride solution.

[0173] Before inoculation, the N 2 Change to 30% CO, 50% H 2 , 5%CO 2 and 15% CH 4 The gas mixture (Range Fuels syngas) was continuously sparged into the fermentation broth throughout the experiment. A vigorous growing culture of Clostridium autoethanogenum was inoculated onto the CSTR at a volume of approximately 10% (v / v). Depending on the growth o...

Abstract

The present invention relates to improvement in efficiency in gasification for use with syngas fermentation. In particular, the invention relates to increasing the overall carbon capture efficiency of a gasification / fermentation process to produce products such as alcohols.

Description

field of invention [0001] The present invention relates to systems and methods for improving overall carbon capture and / or improving the overall efficiency of processes, including microbial fermentation. In particular, the present invention relates to improving carbon capture and / or improving the efficiency of processes including microbial fermentation of CO-comprising syngas substrates. Background of the invention [0002] Ethanol is rapidly becoming the primary fuel for the delivery of hydrogen-rich liquids around the world. Worldwide consumption of ethanol was estimated at 12.2 billion gallons in 2005. The global market for fuel ethanol industry is also expected to witness substantial growth in the future owing to increasing interest in ethanol in Europe, Japan, the United States, and some developing countries. [0003] For example, in the United States, ethanol is used to produce E10 (a blend of 10% ethanol added to gasoline). In E10 blends, the ethanol component acts...
