The role of microorganisms in manganese oxidation and reduction precessing taking part in ground water enviroment is presented.Manganese oxidation catalysed by bacteria takes place in presence of dissolved oxygen, at relatively high Eh conditions about 600 mV and pH 6,5-7 and this process proceeds more rapidly than any non-biological reaction.Chemical oxidation of manganese could be achieved only by raising the pH to 8,5 0r over.Manganese (IV) is reduced already at the Eh value +300 nV and pH values between 6 and 7.The reduction process can be catalysed by bacterial enzymatic systems and coupled with oxidtion of organic matter or indirectly by bacterial metabolites.Occurrence of manganese oxidizing bacteria in ground waters as well as effect of environmantal factors on manganese removal by slow sand filtration is described
