ResumoUtilization of sugarcane bagasses for butanol, ethanol and acetone production was studied by acid hydrolysis and bacterial fermentation. Glucose, xylose and arabinose contents of sugarcane bagasse hydrolyzed in 5% (v/v) sulfuric acid solution were investigated in respective range of 5 to 60 min. Results showed glucose and xylose released during hydrolysis at 121 C and long treatment time of 60 minutes had high concentrations of 18.7 and 19.8 g/l, respectively. The sugarcane bagasse hydrolysate was then used for butanol, ethanol and acetone production by anaerobic fermentation using C.butyricum , C. sporogenes , C.beijerinckii and C.acetobutylicum . The maximum production based on solvent yield was 4.7 g/l butanol, 6.3 g/l ethanol and 9.7 g/l acetone obtained from fermentation of sugarcane bagasse hydrolysate using C. beijerinckii for 48 hours in the presence of 0.5% (w/v) sugarcane bagasse.
