| 英文摘要 | Mariculture is one of the major seafood supplies worldwide and has caused serious environmental concerns on the coastal zone. Its rapid development has been shown to disrupt the sediment ecosystems and thus influence the benthic bacterial communities. Bacterial diversity and community structure within both adjacent farms and non-cultured zones intertidal sediments along the coasts of Qinhuangdao and Dalian, China, were investigated using full-length 16S rRNA gene-based T-RFLP analyses and clone library construction. Richness and Shannon-Wiener index were significantly increased at sites adjacent the mariculture farm with mean values of 29 and 2.97 from peak profiles of T-RFLP result. Clustering analyses suggested that impacts of mariculture on bacterial diversity of sediment were significantly larger than those resulted from temporal and spatial scales. Upon comparisons of RFLP patterns from 602 clones from libraries of the selected five samples, 137 OTUs were retrieved. Members of gamma- and delta-Proteobacteria, Bacilli, Flavobacteria, and Actinobacteria were recorded in all libraries. In addition, gamma-Proteobacteria were dominant in all samples (21.7 similar to 45.0 %). Redundancy analysis revealed that the distribution of bacterial composition seemed to be determined by the variables of salinity, PO4 (3-)-P, NH4 (+)-N, and Chlorophyll a content. The phyla of gamma-Proteobacteria, Clostridia, Flavobacteria, Bacilli, and Planctomycetes were principal components to contribute to the bacterial differences of clone libraries. Our finding demonstrated that these phyla could display variations of bacterial composition linked to environmental disturbance resulted from mariculture. |
