| Abstract | Butanol production from sugarcane juice by Clostridium acetobutylicum ATCC 824 was studied in batch fermentation at 35 ?C and pH 5.0. In a comparative study of fermentation performance between using glucose medium and sugarcane juice medium at the initial reducing sugar concentration of 45 g/L, the total solvent concentrations of 16.62 and 7.89 g/L were obtained from the system using glucose medium and sugarcane juice medium, respectively. The inhibition of butanol fermentation at initial glucose concentrations above 60 g/L was reported. On the other hand, since sugarcane juice is composed predominantly of sucrose, enhancement of butanol formation and total solvent production were achieved by the utilization of sugarcane juice medium with the initial sugar concentration of 80-90 g/L. By utilization of sugarcane juice medium at the optimal sugar concentration (80 g/L), the total solvents of 24.73 g/L (composed of 15.35 g/L butanol, 4.58 g/L acetone and 4.80 g/L ethanol) with the conversion yield (Yp/s) of 32.67% and 0.26 g/(L?h) production rate was obtained |
