Bioplastic

Polyhydroxyalkanoates (PHAs), e.g., po1yhydroxybutyrate (PHB), are synthesized from Acetyl co.A used as precursor, and are used for the synthesis of biodegradable plastics with thermoplastic properties. 

At present, PHAs are produced by bacterial fermentation based on Ralstonia eutropha.
