Alkaline pretreatment and enzymatic hydrolysis of corn stover for bioethanol production

The demand for ethanol in Brazil is growing. However, although the country one of largest producers this fuel, it still necessary to diversify production matrix. In that regard, studies with different raw materials are needed, mainly use low cost and high available wastes such as lignocellulosic residues from agriculture. Therefore, study aimed analyze bioethanol corn stover. An alkaline pretreatment (CaO) was carried out, followed by enzymatic hydrolysis (Cellic Ctec2 Cellic Htec2) obtain fermentable sugars. best experimental condition steps resulted a solution 0.31 gsugar?gbiomass-1. Then, fermentation performed industrial strain Saccharomyces cerevisiae (PE-2) wild yeast Wickerhamomyces sp. (UFFS-CE-3.1.2). yield obtained 0.38 gethanol?gdry biomass-1 was, demonstrating potential process production.
