  • Publication number: 20220372537
    Abstract: The invention relates to a metabolic enzyme-disrupted aerobic strain and a method for culturing the strain. The present invention provides, for example, a culture comprising a culture medium that has been cultured under an aerobic condition, wherein the culture medium contains an aerobe, wherein the aerobe has a disrupted gene encoding a metabolic enzyme of glycolysis selected from the group consisting of the metabolic enzymes of glycolysis except hexokinase, thereby suppressing metabolism from a carbon source (e.g., glucose) to the TCA cycle in the aerobe.

  • Patent number: 10632881
    Abstract: An osmosis membrane is disposed at the boundary between a three-dimensional network structure section and a foam section. The osmosis membrane allows a liquid foam material to permeate. The three-dimensional network structure section is impregnated with the foam material through the osmosis membrane, and subsequently the foam material is solidified, thereby connecting the three-dimensional network structure section and the foam section to each other. The bonded body of the three-dimensional network structure section and the foam section is completed only by disposing the cushion structure component in between the upper mold and the lower mold, and performing a foaming step.

  • Publication number: 20170043509
    Abstract: A three-dimensional network structure is impregnated with a foam material through an osmosis membrane. The foam material is then solidified. The foam material with which the three-dimensional network structure is impregnated is in contact with resin wires of the three-dimensional network on a wide area and is solidified. Thus, a bonded body that comprises the three-dimensional network structure and a foam and has improved connection strength can be manufactured.

  • Patent number: 8798512
    Abstract: A method for producing a printed material, a method for producing a dye-printed material, a printing apparatus, and a dye-printing system have a good transfer property when a dry toner including a dye is electrostatically transferred to a base material, such as a fabric, based on an electrophotographic system or the like. The methods include a step of providing at least one type of dry toner containing a dye component and a binder resin to a charged body, a step of transferring the dry toner from the charged body to a base material, and a step of fixing the dry toner on the base material. In the transfer step, an electric field is applied between the charged body and the base material to fly the dry toner on the charged body from the charged body to the base material.

  • Patent number: 8722919
    Abstract: The present invention provides a method for producing asymmetrical mono-substituted alkylated compounds of ?-amino acids that are represented by a specific formula, using an aldimine-type Schiff base. In the method of the present invention, the process of alkylating an aldimine-type Schiff base in a medium in the presence of an optically-active quaternary ammonium salt phase-transfer catalyst and an inorganic base is initiated, and subsequently the reaction is quenched at a time earlier than a time for completion of the stoichiometric reaction of the alkylation reaction, so that a mono-substituted alkylated product with high optical purity can be obtained.
