  • Labyrinthulid microorganism capable of producing microbial oil, microbial oil, methods for producing said microorganism and for producing said microbial oil, and uses of said microorganism and said microbial oil
    Patent number: 11898190
    Abstract: A method for producing a microbial oil includes steps of: genetically modifying a labyrinthulid by disrupting and/or silencing a gene, or by transforming another gene in addition to the disruption and/or gene silencing of the gene, and culturing the labyrinthulid, such that a fatty acid composition accumulated in the labyrinthulid comprises an increased EPA content; and collecting the microbial oil having the increased EPA content from the labyrinthulid. The labyrinthulid before the modification is selected from (A) a labyrinthulid belonging to the genus Parietichytrium or genus Schizochytrium and having very weak or no activity of producing PUFAs via a PUFA-PKS pathway; and (B) a labyrinthulid belonging to the genus Thraustochytrium in which a host PUFA-PKS gene is disrupted or silenced to a very weak level. The increased EPA content is preferably not less than 11.5% of a total fatty acid composition.

  • LABYRINTHULID MICROORGANISM CAPABLE OF PRODUCING MICROBIAL OIL, MICROBIAL OIL, METHODS FOR PRODUCING SAID MICROORGANISM AND FOR PRODUCING SAID MICROBIAL OIL, AND USES OF SAID MICROORGANISM AND SAID MICROBIAL OIL
    Publication number: 20180320208
    Abstract: A Labyrinthulid microorganism capable of producing a PUFA only through the elongase-desaturase pathway. A Labyrinthulid microorganism which has no ability of producing a PUFA through the endogenous PUFA-PKS pathway or has the ability at an extremely weak level and which has an ability of producing a PUFA through the endogenous elongase-desaturase pathway. The Labyrinthulid microorganism is a microorganism belonging to the genus Parietichytrium or Parietichytrium.
