Abstract

Bioethanol is an alternative and renewable source of sustainable transportation fuels. It is generally considered an environmentally benign source of energy. This study investigated the feasibility of leaves of both Cassava (Manihot esculenta cranz) and Sweet potato (Ipomoea batatas) for bioethanol production using acid pretreatment and hydrolysis and S. cerevisiae as fermenting agent. FTIR spectrum of bioethanol produced confirms the presence of alcohol in the sample while UV-visible spectroscopy was used to determine the concentration of the bioethanol produced. The percentage yield of bioethanol from cassava was 5.09%, 3.50% and 2.31% for 10%, 5% and 2% H2SO4 respectively while sweet potato leaves gave percentage yield of 1.12%, 0.90% and 0.44% for 10%, 5% and 2% H2SO4 respectively. The results supported the bioethanol potential of both samples with the highest yield obtained at 10% sample concentration.
