Butanol production from renewable biomass by clostridia

Combustion Process Analysis in a DISI Engine Fuelled with N-Butanol through UV-VIS Emission Spectroscopy

“…It can be produced from the fermentation of the sugars in biomass. Recently, the use of genetically enhanced bacteria increased the fermentation process productivity [5], [6]. It is expected that a sustainable and cost effective process for butanol production will be realized in the foreseeable future.…”

Can Microbially Derived Advanced Biofuels Ever Compete with Conventional Bioethanol? A Critical Review

“…Although Clostridium can naturally produce isopropanol and butanol, it is a strict anaerobe with a spore-forming life cycle characterized by a slow growth rate (Jones and Woods 1986;Zheng et al 2009;Green 2011;Jang et al 2012). In addition, limited genetic tools were available to engineer solvent production in this organism (Branduardi et al 2014).…”

“…Finally, the status of commercialization of some of the advanced biofuels compared to bioethanol, potential research avenues, and the future perspectives for their commercial success are discussed. In ABE/IBE fermentation, after glycolysis, pyruvate is converted to acetyl-CoA by the enzyme pyruvate ferredoxin oxidoreductases (Ezeji et al 2007;Fischer et al 2008;Zheng et al 2009;Jang et al 2012). Subsequently, two acetyl-CoA molecules undergo Claisen condensation to form acetoacetyl-CoA, which is reduced to 3-hydroxybutyryl-CoA, then dehydrated to form crotonyl-CoA and further reduced to butyryl-CoA, butyraldehyde, and finally butanol ( Fig.…”

“…Subsequently, two acetyl-CoA molecules undergo Claisen condensation to form acetoacetyl-CoA, which is reduced to 3-hydroxybutyryl-CoA, then dehydrated to form crotonyl-CoA and further reduced to butyryl-CoA, butyraldehyde, and finally butanol ( Fig. 1) (Fischer et al 2008;Nielsen et al 2009;Zheng et al 2009;Jang et al 2012). Some of the acetylCoA is converted to acetaldehyde, which in turn is reduced by alcohol dehydrogenase to ethanol (Jones and Wood 1986).…”

Performance and Regulated/Unregulated Emission Evaluation of a Spark Ignition Engine Fueled with Acetone–Butanol–Ethanol and Gasoline Blends

“…The main limitation of producing bio-butanol on a large scale is that the separation process of butanol from the ABE fermentation products requires extra energy consumption and thus increases manufacturing costs [17][18][19][20][21]. This issue has prompted researchers' interests in the possibility of…”
