“…These findings indicate that the archaeal population was less influenced by environmental factors. Among bacteria, Proteobacteria was the main phylum in the sediment at all six sites in both creeks, which was consistent with the results of previous studies of freshwater systems [10,22,54], including Taihu Lake and the Yangtze River estuary [55,56]. As shown in Table S1, Betaproteobacteria was dominant in the sediment of the sewage creek, and the abundance of Betaproteobacteria at the site D1 was higher than at sites D2 and D3.…”

Different characteristics of wastewater have different effects on the diversity and abundance of bacteria and archaea in rivers. There are many creeks around Taihu Lake, and they receive a large volume of industrial wastewater and domestic sewage, which is discharged into these creeks, and finally into Taihu Lake. The present study determined Illumina reads (16S rRNA gene amplicons) to analyze the effects of industrial wastewater and domestic sewage on the bacterial and archaeal communities at the different sampling sites along two creeks. The bacterial and archaeal diversity of the creek receiving sewage was higher than that of the creek receiving industrial waste. Proteobacteria dominated the microbial communities of all samples in both creeks. Betaproteobacteria dominated in the sewage creek, and its abundance declined along the creek. Certain pollutant-resistant classes were more abundant at the site near to the pollution source of the industry creek (e.g., Epsilonproteobacteria and Flavobacteria). Halobacteria belonging to the phylum Euryarchaeota was the dominant archaea at all sites in both creeks, while Methanobacteria was more abundant in the industry creek. The bacterial community was more affected by the distance between the sampling site and the pollutant source than the archaeal community, indicating that bacterial diversity and abundance could be a good index to distinguish domestic and industrial pollution, especially when the main pollution sources are difficult to identify.

“…The other two orders, Enterobacteriales and Legionellales, consisted of chemoorganotrophic pathogens, which were detected at four clone libraries of samples D1-C-09, D2-F-10, Q1-F-09, and Q3-C-10. Interestingly, members of Vibrionales, Pseudomonadales, or Alteromonadales, which were commonly observed in sediment [38,60], were not found in samples of this study.…”

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 γ-and δ-Proteobacteria, Bacilli, Flavobacteria, and Actinobacteria were recorded in all libraries. In addition, γ-Proteobacteria were dominant in all samples (21.7~45.0 %). Redundancy analysis revealed that the distribution of bacterial composition seemed to be determined by the variables of salinity, PO 4 3− -P, NH 4 + -N, and Chlorophyll a content. The phyla of γ-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.

“…These phyla have been always identified as dominant groups in sediment environments and were generally important contributors to biogeochemical processes (Durbin and Teske 2011;Wang et al 2012). Proteobacteria were dominant in most surface marine sediments, comprising >50 % of the microbial biomass (Bowman and McCuaig 2003), and it seems that γ-Proteobacteria was the most significant clade in marine sediments (Feng et al 2009;Wang et al 2012). Global distribution might be an important ecological characteristic of these marine bacteria groups, and many corresponding clusters included might have flexible adaptation to the various marine sediment environments.…”

“…Our results identified 17 bacterial phyla in the sediments of Jiaozhou Bay. To our knowledge, this is among the most diverse coastal sediment habitats in clone library studies so far (Zhang et al 2008;Feng et al 2009). The bacterial diversity in this study is also higher than that of our previous DGGE study, in which the bacterial composition in the sediments collected from ten different Jiaozhou Bay stations in four seasons were evaluated.…”

“…However, in another contaminated D1station, a possible explanation is needed for the conflicting result that δ-Proteobacteria was found significantly less in Aug-D1 samples. It has been demonstrated that the β-Proteobacteria usually constitute a more common fraction in freshwater environment and negatively related to water salinity, as well as they are believed to share the ability to degrade complex organic macromolecules with the Bacteroidetes (Eiler and Bertilsson 2004;Feng et al 2009). In our study, the β-Proteobacteria was the least abundant in station D7, which belongs to the outer bay area and meet the least freshwater input.…”

Purpose Although coastal marine sediments harbor diverse bacteria with important ecological and environmental functions, a comprehensive view of their community characteristics is still lacking in typical environments along the China coast. We studied the diversity and composition of bacterial community in the sediment of Jiaozhou Bay and characterized their spatiotemporal patterns, aiming to analyze the effects of geographic heterogeneity, seasonal difference, anthropogenic activity, and eutrophication gradient on the bacterial ecology. Materials and methods Sixteen full-length bacterial 16S rRNA gene clone libraries were constructed from the sediment bacteria at four stations (A5, B2, D1, and D7) of Jiaozhou Bay over four seasons (February, May, August, and November). The bacterial diversity and community structure variation were analyzed. Results and discussion A total of 1088 16S rRNA gene sequences and 746 distinct operational taxonomic units (OTUs) (at 97 % sequence similarity level) were retrieved from the 16 clone libraries. Libraries of each sample revealed a high diversity, and a total of 17 bacterial phyla were identified.Bacteria lineages Proteobacteria (mostly γ-Proteobacteria and δ-Proteobacteria), Actinobacteria, Bacteroidetes, and Planctomycetes, which are commonly found in marine sediments, were the dominant divisions in our samples. Meanwhile, some uncommon phyla, such as Deinococcus-Thermus and Lentisphaerae, were also detected. Distinct spatial patterns and noticeable seasonal variations of bacteria community were observed, indicating that environmental heterogeneity in spatial variation other than in temporal variation may be more important in determining the bacterial communities. Most of the abundant OTUs were related to sequences retrieved from the heavy-metal-polluted environments, indicating that the Jiaozhou Bay might be influenced by pollution. Conclusions The bacterial communities in Jiaozhou Bay sediments are highly diverse. The four typical stations that we chose might experience different anthropogenic effects and eutrophication gradients, which shaped their bacterial community composition. The environment of Jiaozhou Bay may be under pressure exerted by multi-dimension anthropogenic activities. This study provided a novel insight into the bacterial community variations in Jiaozhou Bay, enriching knowledge about ecological bioindicators and mechanisms that maintain bacterial diversity and shape bacterial community composition.
