  • Isobutanol production using yeasts with modified transporter expression
    Patent number: 9657315
    Abstract: The present invention relates to recombinant microorganisms comprising an isobutanol producing metabolic pathway and methods of using said recombinant microorganisms to produce isobutanol. In various aspects of the invention, the recombinant microorganisms may comprise one or more modifications resulting in the reduction in the expression and/or activity of an endogenous transporter protein. In various embodiments described herein, the recombinant microorganisms may be microorganisms of the Saccharomyces clade, Crabtree-negative yeast microorganisms, Crabtree-positive yeast microorganisms, post-WGD (whole genome duplication) yeast microorganisms, pre-WGD (whole genome duplication) yeast microorganisms, and non-fermenting yeast microorganisms.
    Type: Grant
    Filed: December 21, 2015
    Date of Patent: May 23, 2017
    Assignees: VIB VZW, KATHOLIEKE UNIVERSITEIT LEUVEN, K.U.LEUVEN R&D
    Inventors: Catherine Asleson Dundon, Christopher Smith, Piruz Nahreini, Johan Thevelein, Sofie Saerens
