  • Patent number: 10017793
    Abstract: This invention relates to the metabolic evolution of a microbial organism previously optimized for producing an organic acid in commercially significant quantities under fermentative conditions using a hexose sugar as sole source of carbon in a minimal mineral medium. As a result of this metabolic evolution, the microbial organism acquires the ability to use pentose sugars derived from cellulosic materials for its growth while retaining the original growth kinetics, the rate of organic acid production and the ability to use hexose sugars as a source of carbon. This invention also discloses the genetic change in the microorganism that confers the ability to use both the hexose and pentose sugars simultaneously in the production of commercially significant quantities of organic acids.

  • Patent number: 9957532
    Abstract: This invention relates to improvements in the fermentation process used in the production of organic acids from biological feedstock using bacterial catalysts. The improvements in the fermentation process involve providing a fermentation medium comprising an appropriate form of inorganic carbon, an appropriate amount of aeration and a biocatalyst with an enhanced ability to uptake and assimilate the inorganic carbon into the organic acids. This invention also provides, as a part of an integrated fermentation facility, a novel process for producing a solid source of inorganic carbon by sequestering carbon released from the fermentation in an alkali solution.

  • Patent number: 9845513
    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.

  • Publication number: 20160304431
    Abstract: This invention relates to a process for preparing succinic acid and succinate ester from a succinic acid salt in fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid through biological fermentation. The succinic acid salt in the fermentation process is subjected to double displacement reaction with a strong acid leading to release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with simulated moving bed chromatography to produce succinic acid and succinate ester.

  • Publication number: 20160304912
    Abstract: This invention relates to a process for preparing succinate ester from a succinic acid salt present in a fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid in the form of a succinic acid salt through biological fermentation. The succinic acid salt present in the fermentation broth is subjected to double displacement reaction with a strong acid leading to the release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with an alcohol washing step and subjected to esterification reaction to produce succinate ester which is purified by fractional distillation. The succinate ester thus obtained is converted into 1,4-butanediol, gamma-butyrolactone and tetrahydrofuran through hydrogenation reactions. The succinate ester can also be hydrolyzed to yield highly pure succinic acid.

  • Publication number: 20160160245
    Abstract: This invention relates to the production of succinic acid and other chemicals derived from phosphoenolpyruvate (PEP) by fermentation with a microorganism in which the fermentation medium contains one or more sugars, and in which one or more of the sugars is imported into the cell by facilitated diffusion. As a specific example, succinic acid is produced from a glucose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize glucose 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 that include, for example, glucose, fructose, or sucrose.

  • Publication number: 20150005510
    Abstract: This invention relates to a process for preparing 2-pyrrolidone (also called 2-pyrrolidinone) and N-methylpyrrolidone (also called N-methylpyrrolidinone) from diammonium succinate in fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce diammonium succinate through biological fermentation. In the second stage of this present invention, diammonium succinate is converted into 2-pyrrolidone and N-methylpyrrolidone through a two step reaction.
