“…The results obtained by applying the hydrothermal pretreatment were similar to those obtained for other biomass such as grape stalks, corn stalks, grass (Cynodon dactylon), sorghum, wood, olive tree prunings, eucalyptus, bamboo, wheat straw and sugarcane bagasse (Amendola et al, 2012;Egues et al, 2012;Lee et al, 2009;Rohowsky et al, 2013;Chen et al, 2010;Martin et al, 2010;Alves et al, 2010;Ruiz et al, 2013a;Ruiz et al, 2013b;Abril et al, 2012). Figure 2 shows the results of the morphological analysis of the raw material and solid fraction of the pretreated bagasse by SEM.…”

-Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pretreated bagasse were characterized according to the composition, SEM, X-ray and FTIR analysis. Glucose production after enzymatic hydrolysis of the pretreated bagasse was also evaluated. All these results were used to develop relationships between these parameters to understand better and improve this process. The results showed that the alkaline pretreatment, using sodium hydroxide, was able to reduce the amount of lignin in the sugarcane bagasse, leading to a better performance in glucose production after the pretreatment process and enzymatic hydrolysis. A good xylose production was also observed.

“…A concentração dos ácidos solubilizados da hemicelulose é refletida no perfil de pH do hidrolisado obtido após o pré tratamento, e portanto indica sua severidade. Simultaneamente há solubilização de extrativos, parcial dissolução da lignina e cinzas e solubilização de proteínas (LEE et al, 2009). …”

“…Essa característica exige que ambas as frações (celulose e hemicelulose) obtidas da autohidrólise da biomassa sejam novamente hidrolisadas aos monômeros de açúcares fermentáveis. (LEE et al, 2009 estudaram o efeito da autohidrólise sobre a recuperação das frações celulose, hemicelulose e lignina na biomassa switchgrass. Os autores constataram que o aumento da temperatura foi responsável por aumentar a solubilização da hemicelulose de 30% para 70% quando a temperatura aumentou de 150°C para 190°C, durante o pré tratamento por 20 minutos.…”

“…A more sustainable solution would be to use cellulosic feedstock, which often can be obtained as waste from food crops or from non-food plants grown on marginal land [5]. Lignocellulosic biomass should be pretreated to facilitate biological conversions and to achieve commercial conversion potential [6]. The purpose of pretreatment is to remove lignin and hemicelluloses, reduce cellulose crystallinity and increase the porosity of the materials.…”

Abstract-Lignocellulose ethanol is significantly sustainable bio-fuel. It is an environmentally friendly. This work is to develop a hydrolysis process of pretreated lignocellulose to ethanol production from narrow leaved cattail as a biomass material. Response surface methodology (RSM) with a central composite design (CCD) was followed to optimize the enzymatic saccharification process in order to obtain high glucose yield. Three independent variables (cellulase, β-glucosidase and temperature) that operating condition, vary at CCD five levels (-α, -1, 0, +1, +α). The optimum values for the predicted variables for glucose and xylose released were: cellulase loading 17.5 FPU/g substrate, β-glucosidase loading 0 U/g substrate and hydrolysis temperature 55°C. Under these optimal conditions, glucose and xylose yield reached to 413.25 mg/ g substrate and 75.48 mg/g substrate, respectively. The results of a confirmation experiment under the optimum conditions agreed with model predictions.
