  • Patent number: 9410164
    Abstract: The present invention concerns a method for the biological preparation of prenol comprising culturing a microorganism genetically modified for the bioproduction of prenol, wherein the microorganism comprises a metabolic pathway for conversion of 3-methylcrotonyl-CoA into prenol by the action of an alcohol dehydrogenase enzyme and of an aldehyde dehydrogenase enzyme.
    Type: Grant

    Assignee: METABOLIC EXPLORER
    Inventors: Cedric Boisart, Sr., Guillaume Letellier
  • Patent number: 9384414
    Abstract: A search for a target in a multispectral image is made more efficient and more user-friendly by combining a contrast optimization which is performed locally, with a presentation of a detection image which extends over the entire field of observation (10). The contrast is optimized inside a window (2) of reduced size relative to an image matrix (1) corresponding to the entire field of observation. This window may be moved in conjunction with the direction of observation (D), or it may be selected at will in the image matrix. The detection image may be renewed for each window used, or it may be shared by several windows.

  • Publication number: 20140342419
    Abstract: The present invention is related to a recombinant microorganism engineered for the production of 2,3-butanediol (BDO), wherein said microorganism overexpresses at least one gene encoding a polypeptide involved in the conversion of pyruvate into 2,3-butanediol. The invention is also related to a method of production of 2,3-butanediol comprising the following steps: providing a recombinant microorganism as described above, cultivating the recombinant microorganism in a culture medium containing a source of carbon, and recovering the 2,3-butanediol.
