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...
This work presents a preliminary economic analysis of the production of ethanol using different fermentation processes. The installation of a new plant and the adaptation of an existing ethanol plant to the selective fermentation of glucose from sugar cane hydrolysate were considered. In the latter process, glucose is converted to ethanol and fructose accumulates in the fermentation broth. The use...
