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/g
substrate.
S. cerevisiae, and
P. stipitis showed its ability to ferment glucose and xylose, an abundant C
5 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
