Microbial diversity in polluted harbor sediments II: Sulfate-reducing bacterial community assessment using terminal restriction fragment length polymorphism and clone library of dsrAB gene

Temporal variation of coastal surface sediment bacterial communities along an environmental pollution gradient

“…1) are heavily polluted by heavy metals, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, and a very high concentration of sulfide (HKEPD, 2006). The severity of sediment contamination decreases towards both the eastern (oceanic) and western (the Pearl River estuary) sides, forming a clear pollution gradient (Zhang et al, 2008b).…”

Optimization of biostimulant for bioremediation of contaminated coastal sediment by response surface methodology (RSM) and evaluation of microbial diversity by pyrosequencing

“…This is due to nutrient inputs for microbial development derived from the organic amendments and changes in the microbial community (Bastida et al, 2008). These results reveal that the increased microbial population may be attributed to the increase of sulfate reducing bacteria, which are important regulators of carbon and sulfur cycles in coastal sediments (Zhang et al, 2008;Arndt et al, 2013). …”

Firmicutesis an Important Component of Microbial Communities in Water-Injected and Pristine Oil Reservoirs, Western Siberia, Russia

“…The dsr gene encodes the key enzyme for sulphate reduction -dissimulatory sulphite reductasewhich catalyses the reduction of sulphite to sulphide. DsrAB gene, encoding α-and β-subunits of the enzyme, is widely used as a functional marker of sulphate reduction in studies of SRB diversity using clone library construction, terminal restriction length polymorphism (TRFLP), and stable isotope probing (Pérez-Jiménes and Kerkhof, 2005;Leloup et al 2007;Zhang et al 2008;Handa et al 2010;Pester et al 2010). DsrB gene-targeted denaturating gradient gel electrophoresis (DGGE) has been developed for the rapid detection of sulphate reducing microorganisms in environmental samples (Geets et al 2006).…”
