Stimulation of lycopene synthesis in the mycelium of the mucoraceous fungus Blakeslea trispora was accompanied by major changes in its lipid composition. The phospholipid content in the membrane lip-ids doubled, whereas the sterol and sphingolipid levels changed insignificantly. The amounts of phosphatidyl-choline, phosphatidylethanolamine, and phosphatidic acid in the phospholipids and the triacylglycerol content in the acylglycerols increased. The desaturation degree of fatty acids drastically increased against the background of a decrease in that of the neutral lipids. The data obtained are discussed in relation to the mechanism of action of the lycopene formation stimulator.
