“…The influences of environmental factors on bacterial community compositions had been frequently observed in many environments, such as soils (Valentínvargas, Root, Neilson, Chorover, & Maier, ), lakes (Berdjeb, Ghiglione, Domaizon, & Jacquet, ), ocean (Dang et al, ) and aquaculture areas (Zhang, Wang, & Rong, ). The effects of environmental factors on water microbial communities have been investigated in shrimp cultural enclosure ecosystems and indicated that S, total phosphate, total nitrogen, T and pH were the most important factors shaping the bacterial communities (Hou et al, ). Large‐scale cultivation of seaweed increased DO and pH but decreased inorganic nutrients, which significantly altered the bacterial community compositions of both water and sediment in the cultivation zone (Xie et al, ).…”
