Abstract

Bioethanol is the ethanol from biomass through hydrolysis and fermentation processes. Raw materials of bioethanol are sugary, starch and fibrous materials. Wastes of corn cobs are one of many sources of fibrous materials. In this study, the effect of enzymatic hydrolysis was determined using corn cobs wastes in bioethanol production. Thirty gram of powdered corn cobs wastes were used for enzymatic hydrolysis. Pretreatment was carried out through hydrolysis and then it was fermented. Parameters such as reducing sugar, quality, concentration, density and viscosity of bioethanol production were determined. 0.167mg/ml, 76cm³, 0.331mg/l, 0.9995g/cm³ and 14.1g/cm³ respectively.
