    Seasonal variations of microbial community in a full scale oil field produced water treatment plant by Q. Xie, S. Bai, Y. Li, L. Liu, S. Wang, J. Xi

    Published 2016-01-01
    “…The community structures of fungi and bacteria were analyzed through polymerase chain reaction–denaturing gradient gel electrophoresis and Illumina high-throughput sequencing, respectively. Chemical oxygen demand effluent concentration achieved lower than 50 mg/L level after the system in both summer and winter, however, chemical oxygen demand removal rates after anaerobic baffled reactor treatment system were significant higher in summer than that in winter, which conformed to the microbial community diversity. …”
