Malic acid production in recombinant yeast |
摘要 |
We disclose a recombinant yeast, wherein the yeast is pyruvate decarboxylase enzyme (PDC) activity negative (PDC-negative) and is functionally transformed with a coding region encoding a pyruvate carboxylase enzyme (PYC) wherein the PYC is active in the cytosol, a coding region encoding a malate dehydrogenase enzyme (MDH) wherein the MDH is active in the cytosol and is not inactivated in the presence of glucose, and a coding region encoding a malic acid transporter protein (MAE). We also disclose a method of producing malic acid by culturing such a yeast in a medium comprising a carbon source and a carbon dioxide source and isolating malic acid from the medium. |
