  • Patent number: 8906667
    Abstract: A method of increasing cellular NADPH levels by expressing one or more genes that encode an enzyme that causes the production of NADPH. The system is combined with other enzymes that require NADPH, thus improving the overall yield of the desired product.
    Type: Grant

    Inventors: Ka-Yiu San, George Bennett, Henry Lin, Irene Martinez, Jiangfeng Zhu
  • Patent number: 8486686
    Abstract: A new culture method for producing high levels of a metabolite, such as succinic acid uses oxygen rich culture without pH adjustment to increase the biomass, acclimation in under oxygen lean conditions having <5% partial pressure of oxygen, and the production of high levels of succinate under oxygen deprived conditions. The method can be performed in a single reactor, and is amenable to efficient scale up.

  • Patent number: 7087402
    Abstract: The present invention is related to a process for selectively transesterifying stanols in mixtures comprising sterols and stanols, and a process for separating sterols from said mixtures. The process of selective transesterification comprises the forming of a reacting mixture by contacting a selective lipase with a reactant mixture comprising sterols and stanols and an ester selected from the group consisting of esters of an organic acid with a short chain aliphatic alcohol. The transetrifying is carried out agitated reactors at pressures below atmospheric pressure and temperatures from 30 to 90° C.

  • Patent number: 7078544
    Abstract: A process for producing steryl or stanyl esters, comprises the steps of: a) forming a reacting mixture by contacting a lipase with a reactant mixture wherein the reactant mixture comprise sterols or stanols and one or more esters selected from the group consisting of esters of a fatty acid with a short chain aliphatic alcohol; b) separating the lipase from the reacting mixture to form a reacted mixture; and c) separating steryl or stanyl esters from the reacted mixture. The reaction is carried out in stirred reactors at pressures below atmospheric pressure and temperatures from 30 to 90° C. The separation of esters from the reacted mixtures is carried out by distillation at low pressures. A process for esterifying sterols or stanols comprise forming a reacting mixture by contacting a lipase with a reactant mixture wherein the reactant mixture comprise sterols or stanols and one or more esters selected from the group consisting of esters of a fatty acid with a short chain aliphatic alcohol.

  • Patent number: 6817864
    Abstract: An infant motor skill developmental aid apparatus is disclosed, which includes a support base having a planar top surface and a bottom surface, a top tray having an opening for accepting an infant upper body, and a connection means connected between the support base and the top tray. Further disclosed is a method of assisting infant motor skill development, which includes providing the infant motor skill developmental aid apparatus; placing an infant inside the apparatus through the opening of the top tray and having the infant sitting on the support base with arms on top of the top tray; adjusting the top tray to an appropriate height depending on the infant age; and having the infant playing inside the apparatus for a period of time. The apparatus and the method enhance infant's acquisition of normal motor and early learning skills.

  • Patent number: 4665615
    Abstract: A disposable blade carriage for straight razors that have a holder member and a guard member pivotally mounted on each other. The blade carriage is removably mounted in a longitudinally extending slot in the holder member. The blade carriage includes a latching mechanism on one end that rigidly attaches the carriage to the holder member and a hook member that prevents it from falling off from the other end.
