This journal article analyzes the microbial ecology of the Rio Tinto, an extreme environment with a rather constant acidic pH and high concentration of heavy metals. Molecular ecology techniques are used to analyze the diversity of this microbial community and community composition is studied by denaturing gradient gel electrophoresis (DGGE) using 16S rRNA and by 16S rRNA gene amplification. The authors suggest a model for the Tinto River system based on the iron cycle. The resource includes a map of Rio Tinto and an illustrated geomicrobiological model.
