ABSTRACT Four pearl millet genotypes were tested for their potential as raw material fuel ethanol production in this study. Ethanol fermentation was performed both flasks on a rotary shaker and 5‐L bioreactor using Saccharomyces cerevisiae (ATCC 24860). For rotary‐shaker fermentation, the final yields 8.7–16.8% (v/v) at dry mass concentrations of 20–35%, efficiencies 90.0–95.6%. efficiency 30% reached 94.2%, which greater than that from (92.9%). Results showed millets, starch basis, comparable to those corn grain sorghum. Because millets have protein lipid contents, distillers dried grains with solubles (DDGS) also had content energy levels did DDGS Therefore, could be feedstock areas too grow
