Microalgae and bacteria communities related to sewage treatments were cultured with activated sludge from a brewery. And then, they were used to treat sewage from the brewery under two experimental conditions:Treatment 1 (Filtered and sterilized sewage) and Treatment 2 (filtered but unsterilized sewage). Compositions of microalgae and bacteria communities were analyzed during the experiments. After 20 days incubation, microbial community structures notably changed in all treatments. Chlamydomonas rhinella and Chlorella sp. became dominant bacteria communities in Treatment 1and Treatment 2, and the abundances of unidentified OPB35increased significantly. But Lysobacterium decreased significantly in two treatments. The removal rates of chemical oxygen demand (COD) in Treat. 1and Treat. 2were 73.7% and 67.2%, respectively. What is more, microalgae grew well in the two treatments. Results showed that microalgae communities significantly influenced bacteria community compositions in Treat. 1and Treat. 2and there were no significantly differences in the removal efficiencies of CODCr in two treatments.
