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

Sin embargo, si bien el país es uno de los mayores productores de este combustible, aún es necesario diversificar la matriz productiva. En este sentido, se requieren estudios con diferentes materias primas, principalmente el uso de residuos de bajo costo y alta disponibilidad, como los residuos lignocelulósicos de la agricultura. Por tanto, este estudio tuvo como objetivo analizar la producción de bioetanol a partir del rastrojo de maíz. Se realizó un pretratamiento alcalino (CaO), seguido de hidrólisis enzimática (Cellic Ctec2 y Cellic Htec2) para obtener azúcares fermentables. La mejor condición experimental para los pasos de pretratamiento e hidrólisis resultó en una solución con 0,31 gazúcar∙gbiomasa-1. Luego, la fermentación fue realizada por la cepa industrial de Saccharomyces cerevisiae (PE-2) y por la cepa de levadura salvaje Wickerhamomyces sp. (UFFS-CE-3.1.2). El rendimiento obtenido fue de 0,38 gettanol∙gbiomasa seca-1, lo que demuestra el potencial de este proceso para la producción de bioetanol.A demanda por etanol no Brasil está crescendo.
