Solid-state fermentation of sweet sorghum to ethanol.
Solid-state fermentation of chopped sweet sorghum particles to ethanol was studied in static flasks using an ethanol tolerant yeast strain. The influence of various process parameters, such as temperature, yeast cell concentration, and moisture content, on the rate and extent of ethanol fermentation was investigated. Optimal values of these parameters were found to be 35 degrees C, 7 x 10(8) cells/g raw sorghum, and 70% moisture level, respectively.
