    Abstract: The invention provides a non-naturally occurring microbial organism having an acetyl-CoA pathway and the capability of utilizing syngas or syngas and methanol. In one embodiment, the invention provides a non-naturally occurring microorganism, comprising one or more exogenous proteins conferring to the microorganism a pathway to convert CO, CO2 and/or H2 to acetyl-coenzyme A (acetyl-CoA), methyl tetrahydrofolate (methyl-THF) or other desired products, wherein the microorganism lacks the ability to convert CO or CO2 and H2 to acetyl-CoA or methyl-THF in the absence of the one or more exogenous proteins. For example, the microbial organism can contain at least one exogenous nucleic acid encoding an enzyme or protein in an acetyl-CoA pathway. The microbial organism is capable of utilizing synthesis gases comprising CO, CO2 and/or H2, alone or in combination with methanol, to produce acetyl-CoA. The invention additionally provides a method for producing acetyl-CoA, for example, by culturing an acetyl-CoA producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding an acetyl-CoA pathway enzyme or protein in a sufficient amount to produce acetyl-CoA, under conditions and for a sufficient period of time to produce acetyl-CoA.

    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.
