Abstract: The production of poly-hydroxyalkanoates (PHA) from the activated sludge subjected to conditions with various oxidation-reduction potentials (ORPs) was investigated. By controlling the dissolved oxygen concentration in the cultural media, the ORP were kept at preset levels of -20, -10, 0, and +10 mV. With glucose as the dedicated carbon source, we have demonstrated a correlating relationship with the ORP's in the culture media to the PHA accumulation rate, the PHA production-yield, cell growth rate, glucose uptakes and 3-hydroxybutyrate to 3-hydroxyvalerate (HB/HV) mole ratios in the PHA copolymers. The highest PHA production yield of 0.26 g/g with HB/HV mole ratio of 8.03 was achieved at +10 mV ORP. We concluded that oxygen plays an important role in PHA accumulation and HB/HV mole ratio activated sludge-to-copolymer PHA conversion process.
