  • L-arabinose assimilation pathway and uses thereof
    Patent number: 10392623
    Abstract: The present invention relates to a new L-arabinose assimilation pathway and uses thereof. In particular, the present invention relates to polypeptides exhibiting L-arabinose isomerase, L-ribulokinase or L-ribulose-5-phosphate-4-epimerase activity, and recombinant host cells expressing said polypeptides. The present invention also relates to a method of producing a fermentation product, preferably ethanol, from an arabinose containing substrate, using a polypeptide or a host cell of the invention.
    Type: Grant
    Filed: February 15, 2016
    Date of Patent: August 27, 2019
    Assignee: DEINOVE
    Inventors: Remi Bernard, Assia Zigha, Pascale Joseph, Jean-Paul Leonetti

  • Process for butanol production
    Patent number: 9434963
    Abstract: This invention comprises a process for the bioconversion of a fermentable carbon source to n-butanol by a microorganism, wherein the microorganism is deficient in at least one gene or protein involved in the four-carbon compounds pathway regulation to improve the four-carbon compounds pathway, particularly by inactivation of the transcriptional repressor rex.
