In the study, EM bacteria and LAS bacteria were found to enhance the growth and lipid production of Scenedesmus obliquus cultivated in municipal wastewater. The results showed that the lipid production of S. obliquus was increased by 36.2% and 21.5% after adding the above-mentioned bacteria, respectively. According to the GC analysis of the lipids, EM bacteria could increase the content of monounsaturated fatty acid in S. obliquus, and thus improving the grade of biodiesel. The analysis of microbial community structure in municipal wastewater showed that the richness and diversity of bacteria in wastewater were increased significantly. In addition, the abundances of β-Proteobacteria、α-Proteobacteria were increased, while the abundance of Bacteroidetes was decreased.
