Efficient Process Development for Cellulosic Ethanol Fermentation from Cassava Pulp

Weeraya Samnuknit, Pailin Boontawan, and Apichat Boontawan
Abstract—Ethanol has gain an increasing popularity to be used as biofuels. Various renewable agricultural feed stocks can be used for the fermentation process especially lignocellulosic materials. Pre-treatment of these materials for lignin removal is essential in order to obtain cellulose and hemi-cellulose. In this work, saccharification of cellulosic cassava pulp employed 2 steps of alkaline pretreatment, and enzymatic conversion. Experimental results showed that the reducing sugar was obtained at about 714 mg/gsubstrate. S. cerevisiae, and P. stipitis showed its ability to ferment glucose and xylose, an abundant C5 monosaccharide in lignocellulose materials. The produced fermentable sugars can be further converted to ethanol to 40.50 g/L. The process development of this particular system still required further pilot scale tests as well as process simulation. These results could pave a way for the application in an industrial scale cellulosic ethanol production
