[Iodine concentration by the fungus Penicillium chrysogenum inhabiting soils of the nonchernozem zone].

The iodine accumulation by strains of microscopic fungi Penecillium chrysogenum isolated from soddy-middle podzolic soils of Kirov region has been studied. It has been shown that fungi are able to accumulate from 5,0 X 10(-5) to 10,2% of iodine depending upon the medium iodine content and the degree of the organisms' tolerance to its high concentrations.

[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.
