Interpretive Summary:

Technical Abstract: Poyhydroxyalkanoates (PHA) are biologically-produced polyesters. These polymers are of great interest due to both their potential production from renewable substrates and their inherent biodegradability. Polyhydroxybutyrate (PHB) is the most common type of biological PHA. However, the material properties PHB are not ideal for replacing flexible plastics. PHA polymers with varied monomer chain length have properties suited to applications where rigidity is not desired. We conducted research genetically modifying various microorganisms (Pseudomonas sp. and Bacillus sp.) to produce PHA from various feedstocks. Different PHA (co)polymers were produced containing C4-C12 monomer units. The physical properties of these polymers were tested and will be described.
