Application

Isobutyl alcohol is a water-soluble aliphatic alcohol that is widely used as a solvent in organic synthesis. It is used in the preparation of vanadium phosphate catalysts for the efficient dehydration of xylose into furfural and selective oxidation of n-butane to maleic anhydride.

The limited supply of fossil resources demands the development of renewable alternatives to petroleum-based products. Here, biobased higher alcohols such as isobutanol are versatile platform molecules for the synthesis of chemical commodities and fuels. Currently, their fermentation-based production is limited

Promising approaches to produce higher alcohols, e.g., isobutanol, using Escherichia coli have been developed with successful results. Here, we translated the isobutanol process from shake flasks to a 1-L bioreactor in order to characterize three E. coli strains. With in
