Assessment of the effect of Enteromorpha prolifera on bacterial community structures in aquaculture environment.


ABSTRACT: In recent years, Enteromorpha prolifera blooms had serious impacts on costal environments and fisheries in China. Nevertheless, the effects of E. prolifera on microbial ecology remain unknown. In this study, for the first time, an Illumina sequencing analysis was used to investigate bacterial communities in source water, aquaculture ponds with E. prolifera, and an aquaculture pond in which E. prolifera -free. Principal coordinate and phylogenic analyses revealed obvious differences among the bacterial communities in the pond water with and without E. prolifera. Abundant bacterial taxa in the E. prolifera-containing pond were generally absent from the pond without E. prolifera. Interestingly, pond water with E. prolifera was dominated by Actinomycetales (> 50%), as well as by anaerobic bacteria in the underlying sediment (Desulfobacterales and Desulfuromonadales (> 20%). Pond water in which E. prolifera-free was dominated by Rhodobacterales (58.19%), as well as aerobic and facultative anaerobic bacteria in the sediment. In addition, the ecological functions of other dominant bacteria, such as Candidatus Aquiluna, Microcella spp., and Marivita spp., should be studied in depth. Overall, massive growth of E. prolifera will have serious effects on bacterial communities, and, thus, it will have an important impact on the environment. The novel findings in this study will be valuable for understanding green tides.
