Analysis of the bacterial community in the two typical intertidal sediments of Bohai Bay, China by pyrosequencing

Response of microbial communities to bioturbation by artificially introducing macrobenthos to mudflat sediments for in situ bioremediation in a typical semi-enclosed bay, southeast China

“…Our results showed that the microbial diversities were high in the intertidal sediments of Sansha Bay, with a average of 3766 ± 76 OTUs per sample. The Shannon index (varied between 6.72 and 6.9, Table 3) was comparable and a slightly lower than previous studies in intertidal sediments in Liaodong Bay (6.72-7.54, Zheng et al, 2014), and Bohai Bay (7.17 and 7.19, Wang et al, 2013), China.…”

Bacterial community compositions in sediment polluted by perfluoroalkyl acids (PFAAs) using Illumina high-throughput sequencing

“…According to two diversity indices (Shannon and Simpson), sample XQ5 had lower community diversity (6.76 and 0.0711) compared to the other samples with indices of 8.58-9.89 and 0.003-0.0185, respectively ( Table 2). The diversity and richness of sediment samples from Xiaoqing River were similar to intertidal sediment samples from Laizhou Bay of Bohai Sea (Wang et al 2013a;Wang et al 2014a). Numerous studies showed that the ecosystem of the Bohai Sea in its coastal environment was heavily polluted and was one of the most degraded areas in China (Ma et al 2001;Yu and Mao 2002;Zhang et al 2009).…”

“…Figure 3 showed that the most abundant and largest phylum was Proteobacteria with 59.42 % of the sequences on average (minimum 50.4 % in XQ1 and maximum 85.1 % in XQ5). Previous studies have shown that Proteobacteria is the prominent phylum in sediment from a drinking water reservoir (Roeske et al 2012) and intertidal zones of Bohai Bay (Wang et al 2013a), industrial wastewaters from steel industrial (Ma et al 2015), pharmaceutical, petroleum refinery and sewage (Ibarbalz et al 2013), soils of livestock-cotton production (Acosta-Martinez et al 2010), and CO 2 gas vent (Saenz de Miera et al 2014). Moreover, the abundance of Proteobacteria was higher when environmental conditions were aggravated, such as an increasing abundance of Proteobacteria in drinking water after chlorine disinfection (Huang et al 2014) and river sediment after huge nitrate injection (Chen et al 2013).…”

Role of environmental factors and microorganisms in determining the fate of polycyclic aromatic hydrocarbons in the marine environment

“…The particle grain size and dissolved oxygen were revealed as the main drivers for bacterial diversity and abundance in estuarine sediments (Wang et al. 2013) and deep ocean waters (Salazar et al. 2015).…”
