Transfer of manganese and ferro ions by manganese bacteria

The experimental results of the redox of manganese and ferro ions by manganese bacteria are described.Under the aerobic conditions,the manganese bacteria can oxidate Mn²⁺ into Mn⁴⁺.In the course of the manganese bacteria multiplication,the continual increase of environmental pH is advantagcous to the oxidation of manganese and the rise of environmental temperature helps the bacteria to speed the oxidation of manganese ions.The manganese bacteria can lastly oxidate Fe²⁺ in the culture containing low valent Ferro into Fe³⁺.its oxidation speed being faster than that of manganese oxide.Under the anaerobic conditions,the manganese bacteria can reduce high valent Ferro in solution into low valent ferro and distinctly lower the environmental pH.
