Pretreatment is one of the approaches to yield the higher saccharification process leading to optimization of ethanol yield. The effect of ultrasonic pretreatment on ethanol production from rice straw was studied. A 0.16 kW/L ultrasonic treatment was applied to treat rice straw during enzymatic hydrolysis and fermentation process. The enzymatic hydrolysis process was carried out at 50°C and pH 4.8...
Rice straw can be utilized to use as a raw material for production of biofuel due to its content with a high amount of sugar in a form of 35-40% w/w cellulose and 25-30% w/w hemicelluloses. The effect of ultrasonic treatment to enhance the saccharification process of the enzymatic hydrolysis from rice straw was investigated. Two frequencies at 20 and 24 kHz of ultrasonic treatment were used for 80...
