Resistance to cellobiose lipids and specific features of lipid composition in yeast
2016
Kulakovskaya, E. V. | Mironov, A. A.
The significance of the fatty acid composition and ergosterol content in cells for resistance to cellobiose lipids has been investigated in the cells of mutant Saccharomyces cerevisiae strains that are unable to produce ergosterol or sphingomyelin and in the cells of microorganisms that produce cellobiose lipids. S. cerevisiae mutants were shown to be less sensitive to cellobiose lipids from Cryptococcus humicola than the wild-type strain, and the strains that produced cellobiose lipids were virtually insensitive to this compound as well. The sensitivity of Pseudozyma fusiformata yeast to its own cellobiose lipids was reduced under conditions that favored the production of these compounds. No correlation between the content of ergosterol and sensitivity to cellobiose lipids was observed in S. cerevisiae or in the strains that produced cellobiose lipids. The ratio between the levels of saturated and unsaturated fatty acids in the cells of the mutant strains was correlated to the sensitivity of the cells to cellobiose lipids.
