  • Method for producing cadaverine
    Patent number: 9080190
    Abstract: A method produces cadaverine more efficiently and at a higher yield than production methods by the conventional fermentation methods. The method includes culturing coryneform bacterium/bacteria having an ability to produce cadaverine and having a resistance to 2,2?-thiobis(ethylamine). Preferably, the coryneform bacterium/bacteria has/have lysine decarboxylase activity and, preferably, the coryneform bacterium/bacteria has/have homoserine auxotrophy and/or a resistance to S-(2-aminoethyl)-L-cysteine.
    Type: Grant
    Filed: December 8, 2011
    Date of Patent: July 14, 2015
    Assignee: Toray Industries, Inc.
    Inventors: Nanami Sasaki, Takashi Mimitsuka, Hideki Sawai, Kenji Sawai
  • Method for producing cadaverine
    Patent number: 8999681
    Abstract: A method of producing cadaverine is more efficient and at a higher yield than production methods by the conventional fermentation methods. The method includes culturing coryneform bacterium/bacteria having a resistance to a pH of 5.5 or less. Preferably, the coryneform bacterium/bacteria has/have lysine decarboxylase activity and, preferably, the coryneform bacterium/bacteria has/have homoserine auxotrophy and/or a resistance to S-(2-aminoethyl)-L-cysteine.

  • METHOD OF PRODUCING LACTIC ACID BY CONTINUOUS FERMENTATION
    Publication number: 20140017746
    Abstract: A method of producing lactic acid by continuous fermentation includes filtering a culture of polyploidy prototrophic yeast having a capacity to produce lactic acid by introduction of a lactate dehydrogenase gene through a porous membrane having an average pore size of not less than 0.01 ?m and less than 1 ?m; and recovering the lactic acid from filtrate while the unfiltered liquid is retained in or returned to the culture and a fermentation feedstock is added to the culture.
