Abstract

The study was aim to evaluate the potential of millet husk in the generation of bioethanol through fermentation using Saccharomyces cerevisiae. Samples of millet husks were obtained from Rugga Waru shafting center of Bado area in Wamakko Local Government and was sun dried. The sample was pre- treated using 600 mls of dilute-sulfuric acid and was later hydrolyzed using the enzyme Aspergillus niger  for five days. The reducing sugar content of the hydrolyzed sample was also obtained to be 0.02 mg/ml. The hydrolyzed samples were fermented using reactivated yeast (Saccharomyces cerevisiae) for five days at 35°C. The fermented broth was finally distilled at 78°C to obtain the bioethanol. The quantity of the bioethanol was (79 g/l) and the concentration of the bioethanol produced was obtained to be (0.621%). The thermal property of the millet husk was also obtained to be -7.907 mg, and the rate of production was high.
