title: [Influence of different types of ionizing radiation on fatty acid profiles of cell lipids in microscopic fungi with radioadaptive properties].
abstract: The fatty acid profiles of strains of dark-pigmented (melanin-containing) species Cladosporium cladosporioides and Hormoconis resinae, and light-pigmented Aspergillus versicolor and Paecilomyces lilacinus, showing radioadaptive properties in comparison with control strains of the same species, which did not have such properties and the influence on them of two (121Sn; 137Cs) types of ionizing radiation have been studied. It was established that the most important fatty acids were hexadecanoic acid (C16:0), octadecanoic acid (C18:0), octadecenoic acid (C18:1) and octadecadienoic acid (C18:2). The strains, showing radioadaptive properties in comparison with control differed in the relative concentrations of saturated and unsaturated fatty acids and some minor components. The two types of radiation had different influence on the fatty acid profiles of the investigated strains. At dark-pigmented species C. cladosportoides, H. resinae the fatty acid unsaturation rate was higher, at strains showing radioadaptive properties (0.98) as against control ones (0.73; 0.9), and at light-pigmented species A. versicolor and P lilacinus--it was lower at strains with radioadaptive properties (1.00; 0.83) as against control ones (1.08; 0.92). The paper is presented in Ukrainian.
