    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: The invention provides a non-naturally occurring microbial organism having n-propanol and isopropanol pathways, 1,4-butanediol (14-BDO) and isopropanol pathways, 1,3-butanediol (13-BDO) and isopropanol pathways or methylacrylic acid (MAA) and isopropanol pathways. The microbial organism contains at least one exogenous nucleic acid encoding an enzyme in each of the respective n-propanol, 14-BDO, 13-BDO or MAA and isopropanol pathways. The invention additionally provides a method for co-producing n-propanol and isopropanol, 14-BDO and isopropanol, 13-BDO and isopropanol or MAA and isopropanol. The method can include culturing an n-propanol and an isopropanol co-producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding an n-propanol, an isopropanol, a 14-BDO, a 13-BDO and/or a MAA pathway enzyme in a sufficient amount to produce each of the respective products, under conditions and for a sufficient period of time to produce each of the respective products.
