The Audubon Sugar Institute (ASI), a world leader in sugar processing research, is working diligently to enhance the productivity and profitability of the Louisiana sugar and sugar process-related industries by developing integrated technologies to convert sugarcane bagasse, cane leaf matter and molasses into high value products including ethanol, specialty chemicals, biomaterials and animal feeds. The key biomass components in sugarcane bagasse are cellulose (37-43%), hemicellulose (18-25%) and lignin (22-27%). Ethanol is produced from glucose and xylose after the breakdown of cellulose and hemicellulose, respectively. An ethanol process, utilizing dilute ammonia-treated sugarcane bagasse and molasses as feedstock materials, has successfully been developed at ASI. Our process yields 85% enzyme conversion and 8% (w/w) ethanol at 10% (dry weight) solids loading. Organic acids and glycerol concentrations were determined.
