This study was done to find out the optimized pretreatment for the production of bioethanol from rice husk and to obtain the maximum yield of ethanol by the process of Simultaneous Saccharification and Fermentation. The rice husk homogenized samples were pretreated with 1%, 1.5% and 2% HCl and with 1%, 2% and 3% NaOH solution. The pretreated samples were used for Simultaneous Saccharification and Fermentation (SSF) at 28 ± 2°C at 120 rpm. It has been found through analysis of 3,5-Dinitrosalicylic Acid (DNSA), FTIR and GC that 2% HCl pretreated sample and 3% NaOH pretreated samples resulted into maximum ethanol yield of 6.34% and 5.89% respectively.
