Abstract:
Biobutanol is one of the most attractive biofuels because it has higher energy content, less corrosive, and better miscible with gasoline than ethanol. It can be produced by Acetone-Butanol-Ethanol (ABE) fermentation using Clostridium species. Cell immobilized technique, which is proven to enhance cell density, stable operation, and microbe tolerance compared with free cell system, is applied in the present work. The support for cell immobilization should be inexpensive, stable, reusable, and nontoxic materials. Granular activated carbon derived from coconut shell, having a highly porous material and high surface area with a large adsorption capacity, has been considered as the immobilized material for the ABE fermentation process. Clostridium beijerinckii TISTR 1461 is adsorbed onto granular activated carbon, which is treated with various chemicals to find the optimal treatment conditions. Butanol concentration, pH, cell growth, and glucose consumption, are analyzed and compared to a free cell system. Treated granular activated with 3-aminopropyltriethoxysilane (APTES) provided 15.33 g/l of butanol concentration and the highest coefficient butanol concentration compared to other treatment conditions.
