“…Although no previous study has reported on the metabolism of acetic acid to ethanol by LAB, several species of Clostridia have been reported to express metabolic pathways for the conversion of acetic acid to ethanol (25). In addition, the overexpression of adhE gene, which encodes coenzyme A (CoA)-linked acetaldehyde dehydrogenase and alcohol dehydrogenase, was reported to be a result of the increase in NADH/NAD þ ratio in E. coli (26,27).…”

“…Another technology that can provide a platform for ethanol utilization is Guerbet ethanol condensation chemistry. This process converts ethanol to a versatile building block compound, 1-butanol, which can be readily converted to fuel compounds, such as jet fuel and diesel, or chemical compounds, such as solvents and flavoring agents [7,8]. A basic oxide material, such as magnesium oxide (MgO), is used as catalyst for the ethanol condensation reaction [9].…”

In the base catalyzed ethanol condensation reactions, the calcined MgO-Al 2 O 3 derived hydrotalcites used broadly as catalytic material and the calcination temperature plays a big role in determining the catalytic activity. The characteristics of the hydrotalcite material treated between catalytically relevant temperatures 450 and 800°C have been studied with respect to the physical, chemical, and structural properties and compared with catalytic activity testing. With the increasing calcination temperature, the total measured catalytic basicity dropped linearly with the calcination temperature and the total measured acidity stayed the same for all the calcination temperatures except 800°C. However, the catalyst activity testing does not show any direct correlation between the measured catalytic basicity and the catalyst activity to the ethanol condensation reaction to form 1-butanol. The highest ethanol conversion of 44 % with 1-butanol selectivity of 50 % was achieved for the 600°C calcined hydrotalcite material.

Abstract-Acute energy crisis and the fast depletion of fossil fuel reserves globally has aroused the research interest of scientists all over the world to find out sustainable technologies for biofuel production. Although in the modern era several biofuels such as bioethanol, biodiesel, etc. exists, however, the research focus is shifting towards biobutanol because of its astonishing potential for replacing gasoline as a solo fuel in gasoline internal combustion engines without revamping them, and hence it has got the synonym as biogasoline. Moreover, biobutanol is superior to bioethanol in terms of energy content, moisture affinity and blending capacities. Biobutanol is produced from lignocellulosic biomasses which are not only renewable but also abundantly found either at a cheaper price or even free. Most importantly these biomasses do not compete with food crop biomasses. Biobutanol production is essentially based on anaerobic (ABE) fermentation of lignocellulosic biomasses by solventogenic Clostridium acetobutylicum bacteria. This article will represent a brief review on biobutanol production from lignocellulosic biomasses by ABE (acetone-butanol-ethanol) fermentation process.
