  • Publication number: 20130337519
    Abstract: This invention relates to the production of chemicals by fermentation with a microorganism in which the fermentation medium contains the sugar sucrose. As a specific example, succinic acid is produced from a sucrose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize sucrose as a carbon and energy source. The biocatalysts of the present invention are derived from the genetic manipulation of parental strains that were originally constructed with the goal to produce one or more chemicals (for example succinic acid and/or a salt of succinic acid) at a commercial scale using feedstocks other than sucrose. The genetic manipulations of the present invention involve the introduction of exogenous genes involved in the transport and metabolism of sucrose into the parental strains.

Described herein are compositions and methods for generating neomorphic (R)-2-hydroxyacid dehydrogenases capable of enzymatically converting a 1-carboxy-2-ketoacid to a 1-carboxy-(R)-2-hydroxyacid, or the reverse reaction. Illustrative examples include (a) (R)-2-hydroxyadipate dehydrogenase and uses thereof for converting 2-oxoadipate to (R)-2-hydroxyadipate, or the reverse reaction; and (b) (R)-2-hydroxyglutarate dehydrogenase and uses thereof for converting 2-oxoglutarate to (R)-2-hydroxyglutarate, or the reverse reaction. Also described herein are compositions and methods for generating non-natural microbial organisms to enzymatically convert 2-oxoadipate to (E)-2-hexenedioate or adipate, or to enzymatically convert 2-oxoglutarate to (E)-2-pentenedioate or glutarate, or the respective reverse reactions.

  • Publication number: 20130252294
    Abstract: Disclosed herein are methods for producing compounds (such as 3,4-dihydroxybenzoate, catechol, cis,cis-muconate, or ?-carboxy-cis,cis-muconic acid) utilizing biosynthetic pathways in prokaryotic organisms expressing one or more heterologous genes. In some embodiments, the method includes expressing a heterologous asbF gene (for example, a gene having dehydroshikimate dehydratase activity) in a prokaryotic cell under conditions sufficient to produce the one or more compounds and purifying the compound. In additional embodiments, the method further includes expressing one or more of a heterologous 3,4-DHB decarboxylase gene, a heterologous catechol 1,2-dioxygenase gene, and a heterologous 3,4-DHB dioxygenase gene in the prokaryotic cell and purifying the compound.

  • Publication number: 20130225714
    Abstract: Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce ethanol and/or butanol, e.g., by fermentation.
