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

Isobutanol is an excellent alternative biofuel. Fermentative production of isobutanol had been realized in several microorganisms by combining branched-chain amino acids synthetic pathway and Ehrlich pathway.
