Recombinant microorganism having increased ability to produce isopropanol and method of producing isopropanol using same

Abstract

Disclosed are an expression cassette for isopropanol production, a recombinant vector for isopropanol production expression cassette, a including the recombinant microorganism for isopropanol production into which the vector is introduced, and a method of producing isopropanol using the recombinant microorganism. The recombinant microorganism in which a succinic acid bypass metabolic pathway is introduced to an isopropanol production pathway has very high ability to produce isopropanol. The recombinant microorganism is capable of producing isopropanol in an amount corresponding to about 100 times the maximum amount of isopropanol that is produced using known Corynebacterium glutamicum, and thus can effectively produce isopropanol and can be useful in various industrial fields where isopropanol is utilized. The use of the recombinant microorganism makes possible eco-friendly production of high-value-added isopropanol materials for manufacturing biomass-derived chemical products using glucose in lieu of petroleum.
