Title:
2-ヒドロキシ酸モノマーを含む生体吸収性ポリマー
Document Type and Number:
Japanese Patent JP4780961
Kind Code:
B2
Abstract:
The present invention relates to a method of producing 2-hydroxyacid-containing polymer comprising expressing in an organism genes encoding a polyhydroxyalkanoate (PHA) synthase and at least one enzyme for the production of 2-hydroxyacyl Co-A. Preferably the method is a method of producing glycolic acid-containing polyhydroxyalkanoate polymer comprising feeding glycolic acid or a substrate converted to 2-hydroxyacid units to bacteria or plants expressing a polyhydroxyalkanoate (PHA) synthase and at least one enzyme for the production of 2-hydroxyacyl Co-A to produce the glycolic acid-containing polymer. The present invention also relates to the use of a laser to prepare a porous PHA polymer, by melt or solvent processing the PHA into a mold and perforating the material with the laser to achieve the desired porosity.
