Abstract:
Production of green energy from waste material has played an important role in recent years due to the depletion of non renewable energy sources. Starchy materials, especially maize, are widely used for the ethanol production, but banana peels are waste materials and generated in large quantity every day. The present study was done to investigate optimum parameters for bio-ethanol production from waste banana peels by Saccharomyces cerevisiae. Ethanol was produced from banana peels at different pH ranges from 5.0 to 8.0 and using temperature range from 25 ºC to 55 ºC. Liberated sugars were measured using 3, 5-dinitrosalicylic acid and product was determined by iodometric method. Highest ethanol was found to be produced at pH 6.5 with temperature of incubation 30 ºC.
