    摘要: Provided herein are compositions and methods for the heterologous production of acetyl-CoA-derived isoprenoids in a host cell. In some embodiments, the host cell is genetically modified to comprise a heterologous nucleotide sequence encoding an acetaldehyde dehydrogenase, acetylating (ADA, E.C. 1.2.1.10) and an MEV pathway comprising an NADH-using HMG-CoA reductase. In some embodiments, the host cell is genetically modified to comprise a heterologous nucleotide sequence encoding an ADA and an MEV pathway comprising an acetoacetyl-CoA synthase. In some embodiments, the genetically modified host cell further comprises one or more heterologous nucleotide sequences encoding a phosphoketolase and a phosphotransacetylase. In some embodiments, the genetically modified host cell further comprises a functional disruption of the native PDH-bypass. The compositions and methods described herein provide an energy-efficient yet redox balanced route for the heterologous production of acetyl-CoA-derived isoprenoids.

    摘要: The present invention relates to a simple and economic method of extracting a crystalline Carotenoid compound, such as Beta-carotene, Lycopene, with a purity of at least 99%. The present invention further describes a process to prepare such a highly pure crystalline Carotenoid compound from microbial biomass, using an Anti-purity compound removal process followed by a mono-solvent extraction method. Further the process describes value addition of the co-products recovered during the extraction process thus resulting in a highly economical industrial method for the production of such high purity crystalline Carotenoids compound.

    摘要: Yeast strains capable of increased prenyl phosphate production are provided, enabling increased terpenoid molecule production. Heterologous yeast strains with high prenyl phosphate availability are prepared using one or both of two different strategies for increasing the availability of prenyl phosphates for terpenoid production. First, by co- expressing multiple mevalonate pathway gene analogs, a novel heterologous combination of genes results, some of which increases the inherent availability of prenyl phosphates in yeast. Second, by expressing the non-endogenous enzyme ATP citrate lysase (ACL), a buildup of high cytosolic concentration of acetyl-CoA is produced in the cytosol of S. cerevisiae.
