The oleaginous yeast, Rhodotorula gracilis (CBS 3043) is capable of accumulating large amounts of storage lipid when grown under nitrogen-limiting conditions. The storage lipids produced under these conditions are located in intracellular storage vesicles, and are primarily triacylglycerols. The major fatty acids present in the acyl lipids have been shown to be palmitic, stearic, oleic, linoleic and α-linolenic acids; indicating the presence of Δ9, A12 and Δ15 desaturase enzymes.
