Oxidation of manganous salts of manganese by soil fungi
The microbiological analysis of soils from Ontario, Yukon, and Northwest Territories showed the presence of manganese-oxidizing bacteria, Actinomycetes, and fungi. Bacteria and Actinomycetes were predominant in boreal and tundra soils whereas fungi were predominant in the Ontario samples. The 18 spe...
