    摘要： The present disclosure provides a non-naturally occurring microorganism comprising: one or more polynucleotides encoding one or more enzymes in a pathway that produces acetyl-CoA; one or more polynucleotides encoding one or more enzymes in a pathway that catalyze a conversion of crotonyl alcohol, 5-hydroxy-3-ketovaleryl-CoA, 3-ketopent-4-enoyl-CoA, or 3,5-ketovaleryl-CoA to butadiene; one or more polynucleotides encoding one or more enzymes in a pathway that catalyze a conversion of dihydroxyacetone-phosphate to 1-propanol and/or 1,2-propanediol, wherein the microorganism has reduced levels of pyruvate decarboxylase enzymatic activity (e.g., the microorganism comprises a disruption of one or more enzymes that decarboxylate pyruvate and/or a disruption of one or more transcription factors of one or more enzymes that decarboxylate pyruvate), and wherein the microorganism is capable of growing on a C6 sugar as a sole carbon source under anaerobic conditions. Also provided are methods of using the disclosed non-naturally occurring microorganisms in methods for the coproduction of butadiene and 1-propanol and/or 1,2-propanediol.
