Question

Bacteria responsible for oxidizing ferrous to ferric form under acidic environment is

Answer 1

Iron-oxidizing bacteria are chemotrophic bacteria that derive the energy they need to live and multiply by oxidizing dissolved ferrous iron. They are known to grow and proliferate in waters containing iron concentrations as low as 0.1 mg/L. However, at least 0.3 ppm of dissolved oxygen is needed to carry out oxidation.

Answer 2

hi frnd

The best known form of this reaction is the oxidation of the Fe(II)S mineral known as pyrite, which plays a central role in acid mine drainage, the cause of acidic lakes and rivers that contain excessive levels of iron. In the presence of water and O2 the abiotic and biotic reactions below occur
