| Abstract | Butanol, C4H9OH, is an aliphatic saturated alcohol with potential as fuel/fuel additive that can also be used as intermediate in chemical synthesis and as solvent for a wide variety of industrial applications. The increasing demand for using renewable resources as feedstock for the production of chemicals, combined with advances in biotechnology, is generating a renewed interest in fermentative butanol production. In this context, glycerol, generated as a by-product during the production of biodiesel, arises as a potential substrate for butanol production. In Europe alone, the production of glycerol has tripled within the last 10 years and its price has been considerable reduced. Although fermentation of low-grade glycerol to butanol has been proven, there is still place for process optimization. The main goals of the current thesis are to improve the yield of butanol production from glycerol by Clostridium pasteurianum and to reduce the butanol toxicity towards this microorganism. |
