Iron bacteria

Iron bacteria are associated with the origin of deposits of ironstone. For its existence, iron bacteria use the energy that is released in their cells through oxidation, dissolved in water, ferrous compounds:

4Fe(HCO3)2 + O2 + 2H2O = 4Fe(OH)3 + 8CO2 + 58 kcal.

To synthesize 1 g of organic matter, iron bacteria should allocate more than a 400 g Fe(OH)3. Iron bacteria develop and grow in ponds, swamps, and even in water pipes. Negative effects is fouling and clogging of pipes. When the iron bacteria die, Fe(OH)3, which is contained in them, settles to the bottom of reservoirs, over time, this leads to the formation of "bog ore". They are extremely widespread in fresh and marine waters, play an important role in the cycle of iron in nature. Thanks to their ability to live at the bottom of swamps and seas formed a huge amount of deferred ores of iron and manganese.
