The main goal of this research is to study the solid-state fermentation of sorghum-sudangrass, Grazer II (F-1 hybrid of Sorghum vulgare X Sorghum sudanese), to ethanol. Our research focuses on using a modified method of ensiling to produce ethanol directly in the silo. Thirty-eight liters of ethanol/metric ton (L/MT) on a wet-weight basis were produced from sorghum receiving cellulase compared to 23.4 L/MT for sorghum not receiving cellulase additives. Based on total free sugar content, 101 and 84% of theoretical yield are achieved for cellulase-amended and nonamended sorghum, respectively.
