Available in PDF, EPUB and Kindle. Book excerpt: Two approaches to ethanol production via thermophilic mixed culture fermentation of pretreated wood were investigated. The initial studies of wood biodelignification by Chrysosporium pruinosum and subsequent mixed culture fermentation to ethanol using a cellulolytic strain of sporocytophaga and a strain of Bacillus stearothermophilus proved to be premature for a development effort. Studies of the fermentation of SO2/steam-treated poplar by a mixed culture of C. thermocellum and C. thermosaccharolyticum were, however, technically and economically promising. Wood pretreatment to enhance microbial utilization, the microbiology and biochemistry of pure and mixed culture fermentation of cellulose by C. thermocellum and C. thermocellum and C. thermosaccharolyticum, and techniques for improving ethanol tolerance and yield were investigated. Considerable progress in overcoming the technical barriers to efficient ethanol production from wood have been demonstrated; however, additional studies and development work are required before technical feasibility can be established.

Book excerpt: The objective of this research is to demonstrate on a laboratory scale the technical feasibility of the direct microbial conversion of pretreated wood to ethanol. During the first year of this contract, we investigated the feasibility of biologically delignifying wood with C. pruinosum and directly fermenting the pretreated wood to ethanol with a mixed culture. Bench-top fermentations of a thermophilic bacillus growing on glucose and of a mixed culture of thermophilic sporocytophaga (US) and a thermophilic bacillus growing on microcrystalline and amorphous cellulose were evaluated for growth and ethanol production. In the mixed culture fermentation of amorphous and microcrystalline cellulose, the specific rate of substrate depletion was calculated to be 0.087 hr−1 and 0.0346 hr−1, respectively. However, defining the growth requirements of C. pruinosum and sporocytophaga (US) proved more difficult than originally anticipated. In order to achieve the program objectives within the contract period, a revised research plan was developed based upon chemical pretreatment and the direct fermentation of pretreated hardwood to ethanol. In place of the biological delignification pretreatment step, we have substituted a chemically supplemented steam pretreatment step to partially delignify wood and to enhance its accessibility to microbial utilization. Clostridium thermocellum, which ferments cellulose directly to ethanol and acetic acid, has replaced the mixed culture fermentation stage for ethanol production. Research on the production of ethanol from xylose by the thermophilic bacillus ZB-B2 is retained as one means of utilizing the hemicellulose fraction of hardwood. Work on the genetic improvement of the ethanol yields of both cultures by suppressing acetic acid production is also retained. The rationale, experimental approach, and economic considerations of this revised research plan are also presented.
