Influence of copper ions on the fatty acid profiles of soil filamentous fungi.
The fatty acid profiles have been studied for 5 species 4 genera (9 strains) of soil filamentous fungi isolated from Ukrainian soils polluted with heavy metals and reserve territories. Palmitic, stearic, oleic and linoleic acids were found in the highest quantities (up to 66.82%) of the total content of fatty acids of fungi. Fatty acid unsaturation rate in Paecilomyces lilacinus 146 and P. marquandii 153 resistant to copper ions was high (0.85-1.15) under an increase of copper ions concentration in nutrient medium. The same index in the strains of fungi isolated from soils polluted with heavy metals decreased with an increase of copper ions concentration in the medium. Fatty acid unsaturation rate in P. lilacinus 146 and Penicillium velutinum 465 isolated from soils polluted with heavy metals was 2-fold higher than that in the fungal strains isolated from reserve soils.
