  • Isopropyl alcohol-producing bacterium having improved productivity by GntR destruction
    Patent number: 9267156
    Abstract: An isopropyl alcohol-producing Escherichia coli includes an isopropyl alcohol production system, wherein an activity of transcriptional repressor GntR is inactivated, and the isopropyl alcohol-producing Escherichia coli preferably further includes a group of auxiliary enzymes having an enzyme activity expression pattern with which isopropyl alcohol production capacity achieved by the inactivation of the GntR activity is maintained or enhanced. A method of producing isopropyl alcohol includes producing isopropyl alcohol from a plant-derived raw material using the isopropyl alcohol-producing Escherichia coli. A method of producing acetone includes contacting the isopropyl alcohol obtained by the isopropyl alcohol production method with a complex oxide that includes zinc oxide and at least one oxide containing a Group 4 element, and that is prepared by coprecipitation.
