Abstract

The production of bioethanol from cassava peels and sugarcane bagasse was examined using Simultaneous Saccharification and Fermentation (SSF). Acid hydrolysis (5% H2SO4) was used to hydrolyze 20 g, 30 g and 40 g, each of the cassava peels and sugarcane baggase substrates while dried active baker’s yeast strain (Saccharomyces cerevisiae) was further used to ferment the substrates for 7 days. The quantity of bioethanol produced, average yield, density and proximate composition were determined. The quantity of bioethanol produced from cassava peels at 20 g was 12.37 g/cm3, at 30 g was 14.46 g/cm3and at 40 g was 16.07 g/cm3  while that of sugarcane bagasse 20 g was 5.46 g/cm3, at 30 g was 8.03 g/cm3and at 40 g was 10.44 g/cm3 . The aaverage yield for cassava peels was 16 % while that of sugarcane baggase  was 9.03%. The density for cassava peels was 0.871 g/cm3 while that of sugarcane baggase  was 0.893 g/cm3 . While the proximate composition for cassava peels was; moisture (2.18 ± 0.18)%, ash  (12.98 ± 0.78)%, lipid (1.87 ± 0.36)%, fibre (11.96 ± 0.4)%, protein (3.15 ± 0.05)% and carbohydrate (67.39 ± 0.15)% and that of sugarcane bagasse was; moisture (5.03 ± 0.35)%, ash (8.43 ± 0.63)%, lipid (0.81 ± 0.15) %, fibre (22.76 ± 0.51)%. This research showed that bioethanol could be produced from cassava and sugarcane baggase with cassava peels giving a higher quantity of bioethanol over sugarcane baggase.Keywords: Proximate, Bioethanol, Cassava, Sugarcane, Bagasse, yeast, Fermentation
