Abstract:
A non-naturally occurring microbial organism includes a microbial organism having a reductive TCA or Wood-Ljungdahl pathway in which at least one exogenous nucleic acid encoding these pathway enzymes is expressed in a sufficient amount to enhance carbon flux through acetyl-CoA. A method for enhancing carbon flux through acetyl-CoA includes culturing theses non-naturally occurring microbial organisms under conditions and for a sufficient period of time to produce a product having acetyl-CoA as a building block. Another non-naturally occurring microbial organism includes at least one exogenous nucleic acid encoding an enzyme expressed in a sufficient amount to enhance the availability of reducing equivalents in the presence of carbon monoxide or hydrogen, thereby increasing the yield of redox-limited products via carbohydrate-based carbon feedstock. A method for enhancing the availability of reducing equivalents in the presence of carbon monoxide or hydrogen includes culturing this organism for a sufficient period of time to produce a product.
