  • Patent number: 10443077
    Abstract: The present invention relates to a method for the production of itaconic acid, which method comprises fermenting a recombinant cell capable of producing itaconic acid in a suitable fermentation medium, thereby to produce itaconic acid, wherein: (a) the recombinant cell: (i) overexpresses cis-aconitate decarboxylase; and (ii) overexpresses a part of the citric acid cycle and/or has reduced activity of a native metabolic route to acetate and/or lactate; and, optionally, (b) the fermentation is carried out under anaerobic conditions.
    Type: Grant
    Filed: February 16, 2016
    Date of Patent: October 15, 2019
    Assignee: DSM IP ASSETS B.V.

  • Patent number: 8900834
    Abstract: A process for producing polylactic acid (PLA) comprising the steps: fermenting in a fermentation vessel a micro-organism of the genus Monascus in a medium at a pH less than or equal to 5 under conditions which produce lactic acid into the medium, converting the lactic acid produced into lactide, and polymerizing the lactide to form PLA.

  • Publication number: 20080096242
    Abstract: The present invention relates to the field of fermentation technology. In particular the invention relates to fermentation processes for the production of a first and a second fermentation product by a single production organism wherein the first product is in a more reduced state than the substrate and the second fermentation product is in a more oxidised state than the substrate yet in a less oxidised state than the final oxidation product CO2, such that the concurrent synthesis of the first and second product in the organism allows recycling of reducing power and can be performed under (partially) anaerobic conditions. The invention also relates to such processes in which the first and second fermentation products are capable of forming a(n) (insoluble) complex or salt.
