Abstract

BACKGROUND Sugarcane bagasse is a heterogeneous and organized material that needs a pretreatment to access the polysaccharides (cellulose and xylan). The particle size of a non-milled bagasse can influence the xylan and xylose solubilization, as well as the enzymatic hydrolysis of the pretreated material. Using bagasse selected on 16-, 30-, 40- and 50-mesh sieves: xylan solubilization was performed with hydrogen peroxide; xylose was solubilized with diluted sulfuric acid; and enzymatic hydrolysis was conducted for glucose yield evaluation. RESULTS The xylose solubilized by acid pretreatment resulted in a maximum of 6.59 g L(-1)with no influence of particle size. The solubilized xylan showed linear correlation with a variation of 36.18% (16-mesh bagasse) to 71.43% (<50-mesh bagasse). Pretreated material submitted to enzymatic hydrolysis revealed that particle size influenced the pretreatment, increasing the glucose yield. CONCLUSIONS The results showed that non-milled sugarcane bagasse particle size selection positively influenced the solubilization of xylan, improving the enzymatic hydrolysis of the pretreated material.
