  • Patent number: 8431373
    Abstract: Disclosed are recombinant microorganisms for producing organic acids. The recombinant microorganisms express a polypeptide that has the enzymatic activity of an enzyme that is utilized in the pentose phosphate cycle. The recombinant microorganism may include recombinant Actinobacillus succinogenes that has been transformed to express a Zwischenferment (Zwf) gene. The recombinant microorganisms may be useful in fermentation processes for producing organic acids such as succinic acid and lactic acid. Also disclosed are novel plasmids that are useful for transforming microorganisms to produce recombinant microorganisms that express enzymes such as Zwf.
    Type: Grant

  • Patent number: 8431372
    Abstract: This invention is directed to methods of obtaining a high quantity of desired acid salt in a form that is relatively easy to recover. Particularly desired as a recovery product is an organic acid. A salt form of the desired organic acid is formed that is relatively high in concentration and that is relatively soluble in an aqueous medium. The method includes a step of fermenting a fermentable carbon source in the fermentation medium in the presence of a magnesium compound containing oxygen.
