  • METHOD FOR PRODUCING 3-HYDROXYPROPIONIC ACID
    Publication number: 20230340547
    Abstract: Provided is a two-step production method for 3-HP, comprising: a first step of culturing cells at a high concentration; and a second step of producing 3-HP using the high concentration-cultured cells as a catalyst, in which during the two-step culture, the energy and/or coenzyme balance are adjusted to produce 3-HP and/or improve the productivity of 3-HP. The productivity and yield of 3-HP can be improved.

  • METHOD FOR PREPARING 3-HYDROXYPROPIONIC ACID THROUGH TWO STEPS
    Publication number: 20230265466
    Abstract: The present invention relates to a method for preparing 3-hydroxypropionic acid (3-HP) and/or a method for improving the productivity of 3-HP, the methods comprising the steps of: performing high-concentration cell culturing of a 3-HP-producing strain; and (2) isolating high-concentration-cultured cells to inoculate a medium for 3-HP production with same, thereby producing 3-HP, and thus the present invention can improve the productivity and yield of 3-HP.

  • CRYSTALS OF 3-HYDROXYPROPIONATE AND PROCESS OF RECOVERING 3-HYDROXYPROPIONIC ACID
    Publication number: 20230250044
    Abstract: Provided is a process of recovering 3-hydroxypropionic acid and a crystal of 3-hydroxypropionate, wherein the process includes the steps of: forming crystals of 3-hydroxypropionate in a concentrate containing 3-hydroxypropionic acid in an amount of 300 g/L or more in the presence of an alkali metal salt; and separating the crystals of 3-hydroxypropionate from the concentrate and converting into 3-hydroxypropionic acid.
