The production of polyhydroxyalkanoates (PHAs) using Sequencing Batch Reactor (SBR) was investigated. The experiments were performed in two fabricated SBRs (4 L) of different oxidation state. Synthetic wastewater was used as substrate, using C/N/P ratio of 42:10:1. SBR 1 and SBR 2 were operated in aerobic dynamic feeding (ADF) and anaerobic/oxic dynamic feeding (AODF) condition, respectively. ADF provide feast and famine in aerobic condition, while AODF in anaerobic/oxic condition. PHAs production was found high in AODF than AOF. Maximum PHAs content of 40.0% (w/w)of biomass were produced in AODF mode. Produced PHAs structural and thermal property were good.
