Bacteria play an important role in the aquatic ecosystem. In our work, bacterial community structure and assembly mechanisms were studied in Sansha Bay in Fujian Province based on DNA and RNA high-throughput sequencing. Our results revealed that: (1) A total of 1476 operational taxonomic units (OTUs) were detected, and γ-proteobacteria, α-proteobacteria, cyanobacteriia and bacteroidia were the most diverse bacterial groups. (2) γ-proteobacteria, α-proteobacteria, cyanobacteriia and bacteroidia were also the most abundant groups in Sansha Bay both in the DNA and RNA high-throughput sequencing results. The metabolic activities of these four dominant groups were different, and their metabolic activities were mainly regulated by salinity, total nitrogen, nitrite nitrogen and inorganic phosphate concentrations. (3) The bacterial community structure in Sansha Bay was different in spatial scale, and the closer the geographical location was, the more similar the bacterial community structure was. Neutral process was the main assembly mechanism affecting the construction of bacterial community in Sansha Bay. Our results were useful for the understanding the bacterial community structure and assembly mechanism in Sansha Bay, Fujian.
