摘要A laboratory study was conducted on biomass and lipid production by Scenedesmus sp. and the removal of total nitrogen (TN) and total phosphorus (TP) from filtered anaerobically digested piggery wastewater. The dry weight (DW), lipid content and productivity, total nitrogen, and total phosphorus removal rate were assessed in five media: modified soil extract (MSE) medium, 5 % anaerobic digested wastewater (ADWW), 10 % ADWW, 15 % ADWW, and 5 % ADWW supplemented with NaNO3. The highest biomass productivity appeared in the 15 % ADWW group, which was 20.4 % higher than MSE group. The highest lipid content was found in the 5 % ADWW group (31.60 %), while the highest lipid productivity was in the 10 % ADWW group (27.01 mg L-1 day(-1)). Compared with the 5 % ADWW group, the 5 % ADWW group supplemented with NaNO3 had a similar biomass amount but lower lipid content and productivity. The fatty acids percentage of Scenedesmus sp. showed a slight difference in different media, but with the four dominant fatty acids (C16:0, C18:1, C18:2, C18:3) accounting for 87 % of the total fatty acids, suggests that Scenedesmus sp. in ADWW medium was no different than MSE in terms of lipid composition and content. TN removal rates were 82.85, 82.51, 85.85, 91.28, and 78.71 % in groups 1 to 5, and TP removal rates were 53.05, 88.53, 87.77, 88.72, and 80.64 %. Our experiment also shows the feasibility of using ADWW as a substitute of all the elements of MSE medium except for carbon, which would significantly reduce the costs of microalgal culture.
