(JP2000245437-A)   NOVELTY - A microbial symbiotic association of manganese-oxidizing bacteria and algae, is new.    USE - The symbiotic microbial composition are useful for treating Mn-containing waters to cause oxidation and precipitation of the Mn, which can then be recovered from the water and utilized e.g. in the production of dry battery cells, glazes and enamels, steels and glasses.    ADVANTAGE - The symbiotic combination gives economical and effective recovery of heavy metals, especially Mn, from Mn-containing waters. One or more strains of Mn-oxidizing bacteria were inoculated into artificial sea water to which organic nutrients such as peptone or yeast extract had been added, or into 5 times diluted artificial sea water. An aliquot of the liquid was removed to determine the absorption (optical density) at 660 nanometers and the concentration of dissolved Mn2+. Mn dioxide was precipitated out, even in a liquid with a high concentration of salts, and a high concentration of Mn ions can be removed from solution from which Mn dioxide is not precipitated chemically.
