Differences in hyporheic-zone microbial community structure along a heavy-metal contamination gradient

Article Abstract:

Research has been conducted on relationship between hyporheic microbial community structure and fluvially deposited heavy metal concentration in river sediments. The authors describe the study of this relationship carried out via the use of denaturing gradient gel electrophoresis, 16S rRNA gene phylogenetic analysis, quantitative PCR and phospholipid fatty acid analysis.
