R. and Ching Peiching, O. P.}, abstract = {This study aims to optimize bioethanol production from mango peels using Response Surface Methodology (RSM). The effect of temperature (25{\^a}??40oC), yeast concentration (6{\^a}??14 g/ml) and fermentation time (48{\^a}??96 hours) on bioethanol yield was investigated. Prior to the fermentation process, mango peels were treated with 0.25{\^a}??1 (w/v) sulphuric acid. Optimum glucose yield was obtained at 0.25 (w/v) sulphuric acid. RSM using 3-factor 2-level central composite design (CCD) was employed to evaluate and optimize the synthesis parameters. Based on numerical optimization, the optimum fermentation conditions were at 38oC using 6 g/ml yeast for 48 hours, giving a yield of 7.34 g/ml bioethanol. {\^A}{\copyright} 2014 Trans Tech Publications, Switzerland.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84937194001&doi=10.4028\%2fwww.scientific.net\%2fAMM.625.766&partnerID=40&md5=a28f18e4aae590c6c0a2a71cc86aa956} }
