|Abstract:||A media for fermentation of active sludge in wastewater treatment plant of Guangzhou Siming Yantang Diary Corporation were selected through L9(34) table of orthogonal arrays by designing nine different prescriptions for 3 elements, i.e. C, N and P, with 3 levels and the extracts from the cells of the sludge were tested through a series of physical and chemical examinations in present study. The results showed that the optimum culture medium for fermentation gained through various evaluations contained glucose of 8 g, (NH4)2SO4 of 0.25 g, and 0.25 g of KH2PO4 /liter of water. The extracts from the cells were qualitatively identified to be mainly poly-3-hydroxybutyrate by 1H NMR tests, while their concentration was quantitatively to be over 70.61% by GC test. It was also found that their melting points were between 182.2—188.9℃, higher than PHB standard.|
