外文摘要：The community structures of bacteria, the relationships between selected ecological factors and these communities in seawater were investigated in an underground in situ pipe eco-farming system including the underground pipes, the natural mangrove environment and the reservoir in mangroves of the Beilunhe Estuary, Guangxi, China. The seawater samples were collected on August, 1 (high tide), 8 (low tide), 15 (high tide), 2012 in turn. The profiles of Polymerase Chain Reaction-denaturing gradient gel electrophoresis (PCR-DGGE) revealed an insignificantly horizontal variation in the bacterial community indices among the aforementioned areas (p>0.05). However, the diversity indices were significantly higher at the first sampling than the two later ones (p2-) content was considered to be a potential key ecological factor influencing the transformation of bacterial communities. These results imply that the effects of this eco-farming system on the bacterial communities are negligible and this system can be performed normally. ? 2014 Elsevier B.V.
