In china, a lot of reservoirs were constructed to store rainwater and runoff for drink. Much untreated domestic wastewater was discharged into the reservoir making water eutrophic and cyanobacterial bloom. Denitrification dominated by denitrifying bacteria is the main way of self-purification of eutrophic water body. There are intensely ecological interactions between cyanobacteria and bacteria. The bacterial community and abundant, especially heterotrophic bacteria occurred changes during cyanobacterial bloom. However, it is still not clear the changes of denitrifying bacteria community and abundant during the cyanobacterial bloom.nirK, nirS and nosZ are usually studied to reveal the denitrifying bacteria community and abundant. In this study, we used high-throughput sequencing to compare the denitrifying bacteria community structures and abundant during the cyanobacterial bloom at a eutrophic reservoir in southeast china.
