This document relates to using bidirectional, multi-enzymatic scaffolds to biosynthesize cannabinoids in recombinant hosts.

The present specification relates to a transformed yeast strain capable of simultaneously utilizing xylose and glucose as carbon sources, a preparation method thereof and a biofuel production method using the same. The transformed yeast strain transforms a wild-type yeast strain incapable of using xylose as a carbon source and simultaneously convert glucose and xylose, thereby enabling high yield production of a biofuel. The economics and sustainability of the biofuel and biomaterial production processes can be highly enhanced by providing a strain which can easily be converted to a strain capable of producing a biofuel/material in a high yield through an additional modification.

The present disclosure provides thiolases and polypeptide variants of 3-hydroxybutyryl-CoA dehydrogenase, nucleic acids encoding the same, vectors comprising the nucleic acids, and cells comprising the polypeptide variants and/or thiolase, the nucleic acids, and/or the vectors. The present disclosure also provides methods of making and using the same, including methods for culturing cells, and for the production of various products, including 3-hydroxybutyryl-CoA (3-HB-CoA), 3-hydroxybutyraldehyde (3-HBal), 3-hydroxybutyrate (3-HB), 1,3-butanediol (1,3-BDO), and esters and amides thereof, and products made from any of these.

This invention relates to metabolically engineered microorganism strains, such as bacterial strains, in which there is an increased utilization of malonyl-CoA for production of a fatty acid or fatty acid derived product, wherein the modified microorganism produces fatty acyl-CoA intermediates via a malonyl-CoA dependent but malonyl-ACP independent mechanism.

Provided are genetically engineered microorganism that catalyze the synthesis of propane and/or butanol from a suitable substrate such as glucose. Also provided are methods of engineering said genetically engineered microorganism and methods of producing propane and/or butanol using the genetically engineered microorganism.

The invention provides microorganisms and methods for the production of polyhydroxybutyrate (PHB) from gaseous substrates. In particular, the invention provides a non-naturally occurring Wood-Ljungdahl microorganism comprising (a) an enzyme that converts acetyl-CoA to acetoacetyl-CoA, (b) an enzyme that converts acetoacetyl-CoA to 3-hydroxybutyryl-CoA, and (c) an enzyme that converts 3-hydroxybutyryl-CoA to polyhydroxybutyrate, and methods related thereto.

The present invention provides a Clostridium species comprising a non-native gene capable of expressing (R)-3-hydroxybutyryl-Co A dehydrogenase. Also provided is a method of producing (R)-3-hydroxybutyric acid, or a salt thereof, and/or (R) 1,3-butanediol using such Clostridium.

The present disclosure provides recombinant bacteria with elevated production of ethanol and/or n-butanol from ethylene. Methods for the production of the recombinant bacteria, as well as for use thereof for production of ethanol and/or n-butanol are also provided.
