XXII National Bioprocesses Symposium (SINAFERM) XIII Enzymatic Hydrolysis of Biomass Symposium (SHEB)

This study investigated the enzymatic saccharification of alkaline pretreated sugarcane bagasse (PSB) under a variable solid-liquid ratio and the production of second generation ethanol (2G ethanol) by the commercial strain of Saccharomyces cerevisiae. After hydrolysis, monosaccharide concentrations were determined by HPLC. The hydrolysate containing 10% of PSB submitted to 72 h presented the
highest yields of glucose (31.78 g/L) and xylose (10.85 g/L). The alcoholic fermentations were performed with S. cerevisiae and produced 16.15 g/L of ethanol, with volumetric productivity (QP) of 0.69 g/L.h and yield of ethanol as a function of the substrate (YP/S) of 0.48 gethanol/gsugar.
