Title: | Production of Poly-3-Hydroxybutyrate (PHB) by fermentation of active sludge from food plant (II) | Other Title: | 利用食品工廠活性污泥發酵生產PHB的培養基配方研究(二) | Authors: | Chen, R Yang, YH Yu, PHF |
Issue Date: | 2001 | Source: | 农业环境科学学报 (Journal of agro-environmental science), 2001, v. 20, no. 6, p. 424-428 | 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. | Keywords: | Active sludge Culture of fermentation Optimization of preparation |
