Polyhydroxyalkanoates (PHAs) are naturally-occurring biodegradable thermopolyesters accumulated by bacteria. Copolyester of Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] were noted for its high biocompatibility. This makes it an excellent candidate for medical as well as biopharmaceutical applications. A Gram-negative bacteria, Cupriavidus sp. USMAA1020 has the ability to synthesized P(3HB-co-4HB) copolymer with various 4HB monomer compositions.
