[Manganese concentration by microorganisms inhabiting the soils of a manganese biogeochemical province in Georgia].

The concentrating of manganese by microorganisms was studied with bacteria, actinomycetes and fungi inhabiting soils of the manganese biogeochemical province of the Georgian Republic with different content of this element (from 1045 to 296 000 mg/kg of dry weight). The amount (from 4.0 X 10(-3) to 10 per cent per dry substance) and character of manganese accumulation by microorganisms were found to depend on the content of this element in the growth medium, the taxonomic position of microorganisms, and their adaptation to geochemical conditions.
