Abstract Sugar cane bagasse is produced in Brazil as waste of the sugar and ethanol
industries.
This lignocellulosic material is a potential source for second-generation
ethanol production; however a pretreatment stage is essential, which aims at
removing the hemicellulose component by disorganizing the lignocellulosic complex.
In this work sugar cane bagasse was pretreated by diluted acid hydrolysis resulting in
xylose-rich hydrolysates, which could be fermented to ethanol by a strain of the yeast
Pichia stipitis.
Statistical approach was used to investigate the effects of factors
associated with the dilu...
