METHOD FOR MANUFACTURING ALKYL(D)-3-HYDROXYBUTYRATE BY DECOMPOSITION OF BIOPOLYMER

摘要

PURPOSE: Provided is a method for manufacturing alkyl(D)-3-hydroxybutyrate by the decomposition of a biopolymer, thereby optically pure alkyl(D)-3-hydroxybutyrate useful as chiral building block, economically. CONSTITUTION: A method for manufacturing alkyl(D)-3-hydroxybutyrate comprises the steps of; separating and purifying poly 3-hydroxybutyrate accumulated in the cell of a microorganism which biosynthesizes poly 3-hydroxybutyrate(PHB) by cell lysis; and alcohol-hydrolyzing it under acid catalyst.
