Summary The global seagrass bed ecosystem acts as a natural ecological barrier in the littoral coastal zone. In recent years, this has suffered from serious eutrophication and destruction caused by continuous expansion of aquaculture. However, our understanding influence aquaculture on bacterial community remains limited. study, we used 16S amplicon sequencing to evaluate impact feed extract solution composition function epiphytes endophyte communities core Hainan, Thalassia hemprichii . was main factor that significantly affected epiphyte structure leaves but had no marked effect alpha diversity observed. Additionally, T. alleviated effects organic matter, sulfide, nutrients wastewater. promoted proliferation Bacteroidales , Vibrio Desulfobulbaceae Desulfobacteraceae Pseudoalteromonas Paludibacter Marinomonas, Pseudomonas root which can effectively improve digestibility eutrophication. fact, reduce sulfate sulfide oxidize sulfur within seagrass, indicating increase facilitated accumulation with treatment solution, may be reason for degradation wastewater containing high concentrations pollutants. These results suggest although beds withstand low pollutants, emissions should minimized.
