CELLS FOR ITACONIC ACID PRODUCTION

摘要

The present invention relates to a recombinant cell which is capable of producing one or more of itaconic acid,4-methyl itaconate or 1-methyl itaconate, wherein the said recombinant microorganism has been modified in its genome such that it results in a deficiency in the production of a trans-aconitate methyltransferase. A recombinant yeast cell which is capable of producing itaconic acid and which over expresses: -a nucleic 1 acid encoding a polypeptide having cis-aconitate decarboxylase activity; and-one or more nucleic acids encoding polypeptides which separately or together catalyze a reaction towards acetyl CoA,wherein the said recombinant microorganism has been modified in its genome such that it results in a deficiency in the production of a trans- aconitate methyltransferase. These recombinant yeast cells may be used in processes for the production of itaconic acid, 4-methyl itaconate or 1-methyl itaconate.
