Granular structure and process of production thereof

摘要

A capsular structure is provided which does not cause load to the environment and the living things, produced by utilizing PHA having various functionality, enclosing cores at a high density without limitation of the core material. The granular structure has granules coated at least partly with a polyhydroxyalkanoate constituted of monomer units of at least one of 3-hydroxypropionic acid, 3-hydorxy-n-butyric acid, and 3-hydroxy-n-valeric acid.
