The present invention relates to a recombinant E. coli strain producing 1,3-butanediol from glucose and a method for producing 1,3-butanediol using same, in which a recombinant E. coli strain was developed in which a gene of a pathway necessary for biosynthesis of 1,3-BDO from acetyl-CoA is cloned, and a gene of a pathway that interferes with or competes with this pathway is removed, wherein an E. coli strain was developed in which the pathways and genes involved in the conversion of glucose to acetyl COA, the regeneration rate of NADPH used as a cofactor, and the efficient use of the TCA cycle pathway, which are necessary to improve the biosynthetic efficiency of 1,3-BDO, are modified and optimized.

The present invention introduces an innovative approach for the manipulation of microorganisms to generate colored bioplastics. This is achieved by concurrently expressing genes responsible for pigment production and genes involved in bioplastic synthesis within a microbial host. These genes can be synthesized, obtained from a different host through cloning, or naturally occurring within the host organism. The resultant color compounds become encapsulated within the extended bioplastic polymers within the cells, resulting in the formation of naturally pigmented bioplastics.

The present disclosure provides microbial organisms having increased availability of co-factors, such as NADPH, for increasing production of various products, including 1,3-BDO, MMA, (3R)-hydroxybutyl (3R)-hydroxybutyrate, amino acids, 3HB-CoA, adipate, caprolactam, 6-ACA, HMD A, or MAA, and products made from any of these. Also provided are one or more exogenous nucleic acids encoding an enzyme expressed in a sufficient amount to increase availability of NADPH, where the exogenous nucleic acid includes one or more of ATP-NADH kinase, pntAB, nadK, and gapN. Also provided are one or more gene attenuations occurring in genes, such as NDH-2, that result in an increased ratio of NADPH to NADH. Various combinations of the exogenous nucleic acids and gene deletions are also provided in the present disclosure. The present disclosure also provides methods of making and using the same, including methods for culturing cells, and for the production of the various products.
