Abstract

Ethanol produced from lignocellulosic agricultural products and waste is an environmentallyriendly alternative to petroleum-derived fuel. Lignocellulosic biomass is gasified producing synthesis gas, which is composed of CO, CO2, and H2. Synthesis gas is fermented via anaerobic biocatalyst. The bacterium was grown in a fructose-rich medium then concentrated in ethanol production medium for synthesis gas fermentation. While the known ethanol-producing bacterium Clostridium ljungdahlii was used to provide baseline values for synthesis gas utilization and ethanol production, synthesis gas fermentation were conduced with a culture discovered at Mississippi State University. Additionally, efforts were made to isolate other anaerobic cultures capable of fermenting synthesis gas to ethanol.
