Abstract

PITARELO, Ana Paula; SILVA, Thiago Alessandre da; PERALTA-ZAMORA, Patricio Guillermo  and  RAMOS, Luiz Pereira. Effect of moisture content in the steam treatment and enzymatic hydrolysis of sugarcane bagasse. Quím. Nova [online]. 2012, vol.35, n.8, pp. 1502-1509. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422012000800003.

The effect of moisture content in the steam treatment and enzymatic hydrolysis of sugarcane bagasse was evaluated. Steam treatment was perfomed at 195-210 ºC for 4-8 min using cane bagasse with moisture contents in the range 16-100 wt% (dry basis). Increased moisture contents not only had a positive influence in recovery of main cane biomass components but also resulted in better substrates for enzymatic hydrolysis. As a result, drying is not required for optimal pretreatment and enzymatic hydrolysis of sugarcane bagasse, which can be processed into second generation ethanol immediately after crushing and hot water washing.

Keywords : sugarcane bagasse; steam explosion; moisture content.
