Polyhydroxyaikanoates (PHA) are a family of biopolymers produced by many bacteria, they are reported to have 150 hydroxyalkanoate monomers with various structures.PHA and its related technologies are forming an industrial value chain ranging from fermentation, materials, energy to medical fields.In most cases, bacteria produce copolymers consisting of at least two various different monomers such as copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate (PHBV), copolymers of 3-hydroxybutyrate and 3-hydroxyhexanoate (PHBHHx), and copolymers of 3-hydroxyhexanoate, 3-hydroxyoctanoate, 3-hydroxydecanoate and 3-hydroxydodecanoate (short as medium chain-length PHA copolymers).
