Resumo

This work exploited the concept of mechanical fractionation of sugarcane stalks prior to processing in an integrated biorefinery. The use of four sugarcane hybrids assured the broad evaluation of sugarcane genotypes. In all cases, the outermost region of the stalk contained denser tissue, which was suitable for burning in cogeneration systems. In contrast, the core cane was processed for sucrose extraction, which generated a less recalcitrant lignocellulose fraction more amenable to pretreatment and enzymatic hydrolysis. The mass balance of the lignocellulose components along with biorefining indicated that the core cane provided up to 34% enhanced utilization of polysaccharides compared to the sugarcane bagasse, whereas the highest heating value from the sugarcane bagasse and the outermost fractions were similar, (AU)
