Phylogenetic characterization of microbial communities in a full-scale vermifilter treating rural domestic sewage

Distribution and population structure characteristics of microorganisms in urban sewage system

“…was an anaerobic bacteria of Bacillaceae, which only survives in anaerobic environments such as soil, sludge, and human and animal gut. The Phylum Proteobacteria was detected as one of the dominant bacteria in the study, which also was a dominant bacteria in the influent of wastewater treatment systems or in activated sludges of WWTP; the bacteria was applied to treat wastewater in rural domestic sewage systems, but it exhibited low levels in the fecal and surface water samples (McLellan et al 2010;Liu et al 2013). The sewage pipe, manhole, WWTPs influent, and human fecal samples exhibited different taxonomic compositions.…”

Biological characteristics of a denitrifying phosphorus-accumulating bacterium

“…The discovery of these organisms introduces the possibility of solving the contradiction between carbon utilization and sludge age such that nitrogen and phosphorus removal can be achieved simultaneously (Bortone et al, 1999;Lee et al, 2001;Guo et al, 2014). Recently, progress has been made in the isolation of DPAB, with the isolation of DPAB from the genera Acinetobacter (Tsuneda et al, 2006), Alcaligenes (Li et al, 2006), Aeromonas (Wang et al, 2008), Comamonas (Lu et al, 2009), Pseudomonas (Cai et al, 2010), Bacillus (Ma et al, 2011), Paracoccus (Zhang and Wu, 2012;Liu et al, 2013), Planctomycetes (Liu et al, 2013). In this study, a highly efficient synchronous nitrogen and phosphorusremoving DPAB, Thauera, was isolated through screening for phosphorus-removal capability, nitrate-reducing N 2 , and metachromatic granule staining.…”

Removal of antibiotics and antibiotic resistance genes from domestic sewage by constructed wetlands: Optimization of wetland substrates and hydraulic loading

“…Compared to conventional wastewater treatment technologies, CWs have economical and eco-friendly advantages due to their low-cost, easy operation and low maintenance (Puigagut et al, 2008;Faulwetter et al, 2009). Constructed wetland systems have already been used in the treatment of a wide range of wastewaters originated from domestic (Bahgat et al, 1999;Decamp and Warren, 2001;Keffala and Ghrabi, 2005;Nurk et al, 2005;Reyes-Contreras et al, 2012;Adrados et al, 2014;Younger and Henderson, 2014), industrial (Calheiros et al, 2007;Tao et al, 2007;Younger and Henderson, 2014), and agricultural sources (Nguyen, 2000;Tanner et al, 2002;Yeh et al, 2009;Liu et al, 2013a), as well as landfill leachate (Kozub and Liehr, 1999;Sundberg et al, 2007).…”
