Iron cycle

With our Iron cycle analysis, the microbial iron metabolism is determined in your sample. On request we can give you advice on stimulating, preventing or managing iron micro-organisms for your specific situation.

Analysis essentials

  • To determine the presence of microbial iron metabolism
  • To determine the potential for microbial iron metabolism
  • To monitor the potential for microbial iron metabolism in time (does it increase or decrease?)

Content of the package

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

  • Gallionella sp.
  • Geobacter sp.

Background information

Iron is the Earth’s fourth most abundant crustal element. On the surface of the Earth, iron exists naturally in two oxidation states, ferrous (Fe2+) and ferric (Fe3+) iron. Fe0 is a major product of human activities in the melting of ferrous or ferric iron ores to form cast iron.

The iron plays an important role in microbial cell metabolism. Iron oxidation and iron reduction are additionally tied to the cycling of several major nutrients (carbon, oxygen, nitrogen, sulphur) and trace elements (phosphorus, nickel) in the environment. The typical symptoms of the activity of iron bacteria in water supplies are discoloration (yellow to rust-red or brown), reduction in flow rates caused by growth of the bacteria inside pipes, development of thick red or brown coatings on the sides of reservoirs, sometimes repelled to form gelatinous clumps of red to brown filamentous growths and rapid clogging of filter screens.
