Вплив світла різного спектрального складу на жирнокислотні профілі мікроскопічних грибів, виділених із зони відчуження Чорнобильської АЕС

Abstract

The fatty-acid profiles of microscopic fungi isolated from highly radioactive and non-radioactive substrates and the influence of light with different spectral distributions on these profiles are studied. The quantitative and qualitative composition of the fatty acids of cell lipids is analyzed. The most significant for fungal cells were hexadecanoic, cis-9,12-octadecadienoic, cis-9-octadecenoic, and octadecanoic acids. It is shown that the 7-day action of light of different wavelengths leads to quantitative changes in the ratio of unsaturated and saturated fatty acids. These changes are most significant in strains of melanin-containing species C. cladosporoides and H. resinae. The blue light stimulated most actively the synthesis of unsaturated fatty acids, which increases the fluidity of cell membranes.
