摘要
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 increaes of environmental pH is advantageous 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 fastly oxidate Fe2+ in the culture containing low vaient 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 solutioninto low valent ferro and distinctly lower the environmental pH.
