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. In contrast to using plasmid overexpression and inducible promoters, genetically stable Escherichia coli strains
