Despite these advantages there are relatively few studies on ethanol production from sweet – stem sorghum [8–10].
Earlier studies also included the potential of whole sweet sorghum plant juice and its residue for ethanol production [2]. Sugarcane, sweet sorghum and sugar beets are discussed as feed stalks for fuel alcohol fermentation; land availability and
processing costs are reviewed [11]. Several research groups have developed new cultivars with high grain and sugar
yields [12–14]. In the present study, the genotypes were comparatively evaluated for ethanol production under sterilized and unsterilized conditions.
