Plasmids operate as independent genetic elements in microorganism communities. Through horizontal gene transfer (HGT), they can provide their host microorganisms with important functions such as antibiotic resistance and heavy metal resistance. In this study, six metagenomic libraries were constructed with plasmid DNA extracted from influent, activated(More)
In this study, we utilized the Illumina high-throughput metagenomic approach to investigate diversity and abundance of both microbial community and copper resistance genes (CuRGs) in activated sludge (AS) which was enriched under copper selective stress up to 800 mg/L. The raw datasets (~3.5 Gb for each sample, i.e., the copper-enriched AS and the control(More)
O rganisms of the genus Cupriavidus (formerly named Wauter-sia, Ralstonia, or Alcaligenes) are Gram negative, have peritrichously flagellated rods, and are chemoheterotrophic or chemolithotrophic (1). Much attention has been paid to Cupria-vidus isolates due to their capabilities to biodegrade recalcitrant compounds and xenobiotics (2–5). For instance,(More)
A sequencing batch reactor fed mainly by acetate was operated to perform enhanced biological phosphorus removal (EBPR). A short-term pH shock from 7.0 to 6.0 led to a complete loss of phosphate-removing capability and a drastic change of microbial communities. 16S rRNA gene pyrosequencing showed that large proportions of glycogen accumulating organisms(More)
