  • Method for producing a protein and disaccharide using a
    Patent number: 11384379
    Abstract: A method for producing an objective protein and a method for producing a disaccharide are provided. An objective protein is produced by culturing Talaromyces cellulolyticus in a culture medium containing an expression inducer such as gentiobiose. A disaccharide is produced from a saccharide raw material by enzymatic conversion using a disaccharide synthesizing enzyme.

  • Method for producing dicarboxylic acid
    Patent number: 9970031
    Abstract: A method for producing a dicarboxylic acid is provided. A dicarboxylic acid is produced by culturing a bacterium having a dicarboxylic acid-producing ability, which has been modified so that the expression of one or more of the yeeA gene, ynfM gene, yjjP gene, and yjjB gene is increased, in a medium, and collecting the dicarboxylic acid from the medium.
