ABSTRACT:
The invention aims at providing a method of producing a poly-3-hydroxyalkanoic acid,which comprises carrying out a physical disruption treatment of a suspension of poly-3-hydroxyalkanoic acid-containing microbial cells with adding an alkali thereto either continuously or intermittently and, thereafter, separating the poly-3-hydroxyalkanoic acid.
