The influence of different carbon sources such as glucose, sodium acetate, sodium propionate and ethanol for polyhydroxyalkanoates (PHA) storage were studied in details. It was shown that both the cell content and composition of PHA synthesized by microorganisms in activated sludge were different when different carbon sources were used. PHB (polyhydroxybutyrate) was the main PHA if sodium acetate was used as carbon source, while PHV (polydroxyvalerate) become the main PHA when sodium propionate was used. Sodium acetate and sodium propionate as carbon source had higher PHA production, which reached to 40.89% and 40.96% sludge dry weight, respectively . When ethanol used as carbon source, PHA content was 25.69% sludge dry weight. The minimal PHA storage was 20.14% sludge dry weight when glucose was used.read more
