THE COMPOSITION OF FATTY ACIDS OF ASPERGILLUS FUMIGATUS AND PENICILLIUM CANESCENS ISOLATED FROM CITY SOILS
Abstract
Fatty acids composition of Penicillium canescens Sopp. and Aspergillus fumigatus Fresen. isolated from the soils of Blagoveshchensk (the Amur region, Russian Far East) was studied. Linoleic, oleic and palmitic acids are the main fatty acids for both strains. Linoleic acid is the major one (41.1%) in Aspergillus fumigatus micelium, the content of linoleic and oleic acids is almost equal (35.4 and 31.2% respectively) in Penicillium canescens . The percentage of nonsaturated fatty acids (olein, linoleic, linolenoic and others) in a mycelium of Aspergillus fumigatus reached 71.3%, in Penicillium canescens mycelium – 72%. Palmitic and stearic acids were the main ones among saturated fatty acids in the fungi biomass. Penicillium canescens possessed a big variety of minor and trace fatty acids. The results are of interest for the study of fungi adaptive strategy in technogenic ecosystems, and can be used for micromycetes identification.
