Abstract

Spent grain, the residue remaining after extracting is major by-products or agriculture. This cellulose-rich biomass is a source of sugars for fuel ethanol fermentation. In this work, which is basically on the production of Bioethanol from inexpensive raw materials, pretreatment of dried wheat residue was chosen as the suitable method for solubilizing sample before fermentation. Sodium hydroxide was used as the alkaline medium for hydrolysis. Fermentation of hydrolysate was-achieved by the use of yeast and yeast and the average yield of ethanol per volume of hydrolysate was determined to be 1% as opposed to the standard yield of 23% probably due to the presence of yeast inhibitory compounds in wheat chaff.
