Iron Oxidizing Bacteria

With our Iron Oxidizing Bacteria analysis, iron oxidation Gallionella bacteria are determined in your sample. On request we can give you advice on stimulating, preventing or managing Gallionella in your specific situation.

Analysis essentials

  • To determine the potential for microbial iron oxidation
  • To determine the spread of microbial iron oxidising Gallionella species
  • To monitor the potential for microbial iron oxidation in time (does it increase or decrease?)

Content of the package


The following micro-organisms are detected and quantified with our IOB analysis:

  • Gallionella sp.

Background information

Iron oxidizing bacteria like Gallionella gain their energy for growth from the oxidation of ferrous iron (Fe2+) to ferric iron (Fe3+). These bacteria are involved in spoilage of well water, blockages in water pipes and other water quality issues associated with ferric iron precipitates. However, on the other hand they are being seen as potentially useful micro-organisms: bacterial ferric iron oxyhydroxides can be used to adsorb anions such as phosphate, arsenate and humic colloids in polluted and contaminated water. Currently, some IOB are used to solubilise metals from mineral ores or to make it accessible to chemical extraction (bioleaching). This group of micro-organisms therefore is very important for industries all around the world. Gallionella species are widely distributed and can oxidise iron even under highly toxic conditions that are thought to favour only chemical oxidation. They may therfore also be relevant in your situation.
