  • Method of producing chemical substance
    Patent number: 10378029
    Abstract: A method produces a chemical product by continuous fermentation including filtering a culture liquid of a microorganism(s) through a separation membrane, retaining unfiltered liquid in, or refluxing unfiltered liquid to, the culture liquid, adding a fermentation feedstock to the culture liquid, and recovering a product in the filtrate, wherein the microorganism(s) is/are a microorganism(s) that undergo(es) catabolite repression, and the fermentation feedstock comprises hexose and pentose.
    Type: Grant
    Filed: January 11, 2013
    Date of Patent: August 13, 2019
    Assignee: Toray Industries, Inc.
    Inventors: Koji Kobayashi, Shiomi Watanabe, Kyohei Isobe, Kenji Sawai, Kyungsu Na, Shingo Hiramatsu, Katsushige Yamada
  • Method for producing glucosidase, enzyme composition, and method for hydrolyzing biomass
    Patent number: 9034627
    Abstract: A method for producing a mutant glucosidase includes introducing DNA encoding a secretion signal sequence and DNA encoding Asn-X-Ser or Asn-X-Thr into DNA encoding a glucosidase derived from a thermophile, and introducing the resulting DNA into a eukaryotic microorganism and expressing it as a secretory protein. An enzyme composition contains the mutant glucosidase.

  • METHOD OF PRODUCING CHEMICAL SUBSTANCE
    Publication number: 20150024445
    Abstract: A method of producing a chemical product by continuous fermentation includes filtering a culture liquid of a microorganism(s) through a separation membrane; retaining unfiltered liquid in, or refluxing unfiltered liquid to, the culture liquid; adding a fermentation feedstock to the culture liquid; and recovering a product in the filtrate, wherein the fermentation feedstock contains pentose and hexose, and wherein the microorganism(s) is/are a microorganism(s) having a pathway in which pentose reductase and pentol dehydrogenase are used to metabolize pentose.

  • METHOD FOR PRODUCING 1,5-PENTANEDIAMINE
    Publication number: 20130071888
    Abstract: A method of producing 1,5-pentanediamine includes culturing coryneform bacterium having a gene encoding lysine decarboxylase in its chromosome, which coryneform bacterium maintains lysine decarboxylase activity of not less than 50 mU/mg protein during culturing and the gene encoding lysine decarboxylase is linked downstream of a promoter that functions during the logarithmic growth phase.
