[Makeup of the extracellular lipids in Rhodotorula glutinis yeasts].

The fractional composition of extracellular lipids extracted with hexane and ethanol was studied in the yeast Rhodotorula glutinis 35 by thin-layer chromatography. The two extracts of extracellular lipids were found to be similar in composition though differing in the quantitative content of individual fractions. The fractional composition of extracellular lipids differed from that of intracellular lipids. The peculiarity of the fractional composition of extracellular lipids can be accounted for by the specificity of its fatty acid and alcohol composition.
