    • PURPOSE: A particulate construct such as microcapsules utilizing highly functional polymer compound, a producing method thereof, and a method for producing particulate construct such as microcapsules by a bioengineering process are provided. CONSTITUTION: The particulate construct comprises an external phase containing a polyhydroxyalkanoate and constituting a first solid phase; and an internal phase incorporated in the external phase, wherein the internal phase is at least one of a second solid phase, a liquid phase or a gaseous phase. The method for making a particulate construct comprises steps of preparing an oil phase containing polyhydroxyalkanoate and organic solvent; and eliminating the organic solvent and/or water from the oil phase, thereby preparing a particulate construct containing at least one of solid phase, liquid phase and gaseous phase derived from the oil phase. The method for making a particulate construct comprises steps of preparing a water phase containing a polyhydroxyalkanoate synthetase and 3-hydroxyacyl coenzyme A; preparing emulsion by the water phase and an oil phase; polymerizing 3-hydroxyacyl coenzyme A by polyhydroxyalkanoate synthetase to synthesize polyhydroxyalkanoate; and eliminating organic solvent and/or water, thereby preparing a particulate construct containing at least one of solid phase, liquid phase and gaseous phase.
