Sweet sorghum (Sorghum bicolor (L.) Moench) is a drought tolerant energy crop, with a high nitrogen use efficiency, identified as a possible ethanol feedstock because of its biomass yield and high concentration of fermentable free sugars. The cultivation of sweet sorghum is easy and economic, and it could be an alternative in particular regions where conditions are not favorable for growing starch-rich crops, such as maize. Bagasse and stillage are the main by-products of the...
