    摘要： There is disclosed a method of producing isobutanol. In an embodiment, the method includes providing a microorganism transformed with an isobutanol producing pathway containing at least one exogenous gene. The microorganism is selected to produce isobutanol from a carbon source at a yield of at least 10 percent theoretical. The method includes cultivating the microorganism in a culture medium containing a feedstock providing the carbon source, until isobutanol is produced. The method includes recovering the isobutanol. In one embodiment, the microorganism is a yeast with a Crabtree-negative phenotype. In another embodiment, the microorganism is a yeast microorganism with a Crabtree-positive phenotype. There is disclosed a microorganism for producing isobutanol. In an embodiment, the microorganism includes an isobutanol producing pathway containing at least one exogenous gene, and is selected to produce a recoverable quantity of isobutanol from a carbon source at a yield of at least 10 percent theoretical.

    摘要： There are disclosed metabolically-engineered yeast and methods of producing n-butanol. In an embodiment, metabolically-engineered yeast is capable of metabolizing a carbon source to produce n-butanol, at least one pathway produces increased cytosolic acetyl-CoA relative to cytosolic acetyl-CoA produced by a wild-type yeast, and at least one heterologous gene encodes and expresses at least one enzyme for a metabolic pathway capable of utilizing NADH to convert acetyl-CoA to n-butanol. In another embodiment, a method of producing n-butanol includes (a) providing metabolically-engineered yeast capable of metabolizing a carbon source to produce n-butanol, at least one pathway produces increased cytosolic acetyl-CoA relative to cytosolic acetyl-CoA produced by a wild-type yeast, and at least one heterologous gene encodes and expresses at least one enzyme for a metabolic pathway utilizing NADH to convert acetyl-CoA to n-butanol; and (b) culturing the yeast to produce n-butanol. Other embodiments are also disclosed.
