title: Influence of the alkaline delignification on the simultaneous saccharification and fermentation (SSF) of sugar cane bagasse.
abstract: Ethanol production from steam explosion alkaline delignified bagasse was investigated by saccharification and simultaneous fermentation. Non delignified bagasse (ND) contained 25% lignin, and after alkaline delignification, materials with 6% (D1 - NaOH 1% w/v) and 12% (D05 - NaOH 0.5% w/v) lignin, respectively, were obtained. Ethanol production increased 450% and 733% in relation to ND, when D05 and D1 material, respectively, were used. Higher productivity and EtOH/bagasse were observed for D1. However, higher enzymatic convertibility of cellulose was obtained with 0.5% w/v NaOH. Alkaline delignification increased the ethanol production despite decreased cellulose.
