  • Patent number: 9315443
    Abstract: The invention relates to a method for removing an organic compound having one or more positive charges from an aqueous solution. Said method consists of the following steps a) the aqueous solution containing the organic compound, and a hydrophobic organic solution which contains a hydrophobic liquid cation exchanger having one or more negative charges and a negative total charge, are provided, b) the aqueous solution and the organic solution are brought into contact with each other and c) the organic solution is separated from the aqueous solution.

  • Patent number: 9249435
    Abstract: A process for the improved separation of a hydrophobic organic solution from an aqueous culture medium is provided. The process includes preparing an aqueous culture medium of a metabolically active cell having a decreased activity; contacting of the aqueous culture medium with a hydrophobic organic solution comprising a substrate for biotransformation; conducting a biotransformation of the substrate; and separating the hydrophobic organic solution comprising a biotransformed substrate from the aqueous culture medium. The decreased activity of the metabolically active cell is in comparison to a wild-type of the active cell and the decreased activity is of at least of one enzyme that catalyzes one reaction of ?-oxidation of fatty acids.
