  • Method for producing hydroxycarboxylic acids by auto-degradation of polyhydroxyalkanoates
    Patent number: 6472188
    Abstract: The present invention provides a method for producing. optically active hydroxycarboxylic acid monomers by auto-degradation of polyhydroxyalkanoates (PHAs). In particular, the present invention provides a method for producing hydroxycarboxylic acid monomers (mostly optically active in (R)-(−)-configuration) comprising the steps of: (a) synthesizing and accumulating PHAs by culturing various microorganisms; and (b) preparing optically active hydroxycarboxylic acids which are monomers of PHAs, by auto-degradation of PHAs by keeping the cultured microorganism in a degradation solution such as water, salt solution, mixture of water and organic solvents, and buffer solution.
