  • Method for non-homologous transformation of Yarrowia lipolytica
    Patent number: 6582951
    Abstract: The invention concerns the integration of a gene of interest into the genome of a Yarrowia strain devoid of zeta sequences, by transforming said strain using a vector bearing zeta sequences.
    Type: Grant
    Filed: April 27, 2001
    Date of Patent: June 24, 2003
    Assignees: Institut National de la Recherche Agronomique - INRA, Centre National de la Recherche Scientifique - CNRS
    Inventors: Jean-Marc Nicaud, Claude Gaillardin, Georges Pignede
  • Upstream activator sequences and recombinant promoter sequences functional in yarrowia and vectors containing them
    Patent number: 6083717
    Abstract: The invention concerns an upstream activating sequence (UAS) functional in Yarrowia consisting essentially of at least one copy of a selected sequence, and an recombinant promoter sequence comprising such an UAS. It concerns vectors comprising the recombinant promoter sequence and recombinant yeasts containing them, as well as process for producing a protein in yeast.
    Type: Grant
    Filed: January 6, 1998
    Date of Patent: July 4, 2000
    Assignees: Institut National de la Recherche Agronomique, Institut National Agronomique Paris- Grignon
    Inventors: Catherine Madzak, Sylvie Blanchin-Roland, Claude Gaillardin
  • ARS sequence which is efficacious in yarrowia lipolytica
    Patent number: 5212087
    Abstract: The present invention relates to ars sequences which are efficacious in Yarrowia lipolytica, as well as to plasmids carrying these sequences.The strains of Y. lipolytica transformed with the said plasmids may be used in fermentation processes enabling proteins of industrial importance to be prepared.
    Type: Grant
    Filed: January 27, 1989
    Date of Patent: May 18, 1993
    Assignee: Institut National de la Recherche Agronomique (INRA)
    Inventors: Phillippe Fournier, Claude Gaillardin, Bernard Kudla, Henri Heslot
  • Yeasts
    Patent number: 3930946
    Abstract: A process for the preparation of a stable diploid of Candida lipolytica which comprises (a) in a first stage, separately cultivating two haploid strains of Candida lipolytica of opposed sign in a medium rich in assimilable carbon nutrient; (b) in a second stage, cultivating the two resultant strains together in a medium poor in assimilable carbon nutrient; and (c) in a third stage, after the appearance of diploid colonies, treating them with a mutagenic agent to stabilize them. The invention also comprises a process for the preparation of .alpha.-ketoglutaric acid which comprises cultivating a diploid strain obtained by crossing two Candida lipolytica haploid strains of opposite sign in a medium containing, as source of assimilable carbon, at least one hydrocarbon.
