Methods And Microorganisms For Production Of C4-dicarboxylic Acids

Abstract

Methods and recombinant microorganisms for the biological production of C4-dicarboxylic acids are described. The recombinant microorganisms have increased production of OAA as compared to unmodified microorganisms. In some cases, the recombinant microorganisms have been modified to reduce production of pyruvate and/or reduce conversion of pyruvate to acetaldehyde. Thus, the microorganisms are modified to reduce the activity of pyruvate kinase and/or pyruvate decarboxylase.
