| description | Polyhydroxyalkanoate (PHA) is an advantageous polymeric material due to
environmental friendliness but its mechanical properties limits its potential in material
selection. Green composites, produced from renewable polymers such as
thermoplastic PHA and natural fibres, are possible ways to solve this shortcoming. It
can potentially substitute non-renewable synthetic materials in composite
manufacturing sector. The polymer component of the composite, poly(3-
hydroxybutyrate-co-3-hydroxyhexanoate) [P(3HB-co-3HHx)] with 3HHx monomer
fraction of approximately 20 mol%, was biosynthesized by fermentation using used
cooking oil as the sole carbon source. Subsequently, bulk quantity ofP(3HB-co-3HHx)
was recovered using solvent-free novel biological recovery method with yellow
mealworms (Tenebrio molitor) and followed by further purification with water
containing strong anionic detergent. P(3HB-co-3HHx) showed slightly better thermal
stability than its solvent extracted derivative with the removal of inorganic compounds
during the purification process. |
