Abstract

Sugarcane biomass (bagasse) along with other leftover biomass such as corn and sorghum stover is present in large quantities alongside large-scale biofuel-refineries. The utilization of this biomass as a source of fermentable sugars (by degradation of cellulose and hemicellulose) produce second-generation biofuels, which are high priority development items in most BioEnergy Technology Programs. In nature dead biomass is entirely recycled by microbial systems. This means that recalcitrant polymers are decomposed into its utilizable sugar and phenolic components that promote microbial growth producing CO2 and H2O, which in turn is again fixed into sugars and converted into polysaccharides. We hypothesize that for this natural recycling process to take place an enzyme system, rather than individual enzymes are necessary to accomplish complete degradation. Thus, we propose to look at the enzyme system in nature (decomposing sugarcane bagasse) as a whole, determine its genetic basis and reconstruct a heterologous system useable in commercial operations. The sugarcane proteo-genomics project is a collaboration, between Oklahoma State University and the Brazilian Bioethanol Science and Technology Laboratory (CBTE) and interfaces with several local projects such as the Oklahoma Biofuels Center (Elshahed, OBC) and ongoing projects funded by the Department of Energy, United States Department of Agriculture and others.
