    Abstract: Mixed fruit peels (Banana (BP) and Papaya (PP) bioethanol was produced using Saccharomyces cerevisiae. The proximate and compositional analysis of BP and PP was obtained about 6.67% moisture, 5.75% ash, 82.75% volatile matter, and 5% fixed carbon and 1.1gram, 38.1%, 15.7% and 45.1% extractives, hemicellulose, lignin, and cellulose respectively from...
