“…Here we have employed straw and tops separately, reaching 40 g/L of glucose release from the experiments with the tops as a starting biomass and 29 g/L for the straw. This observation suggests that the use of the tops appears to contribute to the high conversion of cellulose to glucose found by Santos et al (2013), which is also probably related to the lower levels of lignin in the composition of the tops (see Table 1). …”

“…It is noteworthy that the results for the sugarcane bagasse were lower in both process steps (see Figures 1 and 2). Santos et al (2013) employed the hydrothermally pretreated trash for the bioethanol production. According to the authors, the step of enzymatic saccharification was significantly improved with the use of this pretreatment technology.…”

“…Response surface analysis is a method that comprises a set of mathematical and statistical procedures used in the model to develop, improve and optimize processes (Zhang et al, 2009;Santos et al, 2014). With surface analysis response, the best conditions of hydrothermal pre-treatment in sugarcane were determined (Ferreira et al, 2015).…”

“…Diferentes fontes de energia renováveis estão sendo estudadas com o objetivo de complementar àquelas derivadas do petróleo. Nesse contexto, as biomassas lignocelulósicas surgem como uma boa alternativa para essa finalidade [1,2,3].…”

“…Ademais, a etapa de deslignificação não promoveu melhora significativa na conversão da celulose a glicose na hidrólise enzimática. Santos et al (2014) [3] realizaram tratamento hidrotérmico da palha de cana, utilizando planejamento experimental (variáveis: temperatura entre 170 e 210 °C, tempo entre 5 e 15 minutos, e concentração palha/água entre 10 e 15%). A melhor condição encontrada no tratamento hidrotérmico foi a 190 °C, 18 minutos e 12,5% de relação palha/água.…”
