Degradation of lignocellulosic biomass and its subsequent utilization for the production of liquid fuels: Subcontract progress report, 1 September 1981-28 February 1982
This project is a coordinated effort to develop process technology for the degradation of lignocellulosic biomass and its utilization for the production of liquid fuels. Current efforts are based on our prior success in developing a single-step microbiological process for the conversion of lignocellulose to ethanol. This process utilizes a mixed culture of Clostridium thermocellum, a thermophilic cellulolytic anaerobe which degrades cellulose and hemicellulose to fermentable sugars, and Clostridium thermosaccharolyticum, a thermophilic anaerobe which produces high concentrations of ethanol from both hexoses and pentoses. The proposed studies will focus on the use of C. thermocellum and its cellulases for enhanced saccharification of lignocellulose and on the direct fermentation of lignocellulose to the liquid fuel, butanol. Efforts on saccharification are directed to facilitate the adoption of existing fermentation ethanol plants for cellulosic substrates and to overcome the rate limiting step of saccharification in the mixed culture. The effort on butanol will extend the concept of direct fermentation to the production of this liquid fuel.
