As biorefineries replace oil refineries, society and the environment will benefit from a switch from hydrocarbon feedstocks to renewable carbohydrates as a source of energy, materials and chemicals. Lignocellulosic biomass-based ethanol technologies are rapidly evolving and bottlenecks are being identified that need to be overcome to achieve widespread commercialization. The study, in this sense, was carried out ammonia percolation (AP) pretreatment using cassava stem as lignocellulosic biomass, performed enzymatic saccharification and fermented into ethanol by Saccharomyces cerevisiae. As results of the pretreatment, the delignification ratio appeared very efficiently of 45% or more (120°C, 120min) and cellulose which can be converted to ethanol was excellently conserved. Also, the result of the saccharification, glucose is obtained 27.4 g/L by enzymatic digestibility. And ethanol concentration reached to 12.4 g/L in 24 h. This study showed not only total process for bioethanol production from agricultural biomass but also efficient pretreatment of lignocellulosic material.
