Thin layer chromatography analyses of Wab+ cells grown under nitrogen limiting and carbon limiting conditions. Cellular lipid compositions of Wab+ cells grown under nutrient limiting conditions for 28 h were analysed from extracted lipid samples proportioned to biomass. In the Figure: std - wax ester standard palmityol palmitate; 1 - Initial lipid composition of the cultivations; 2 - lipids extracted from control cultivation (grown in normal medium); 3 - lipids extracted from low nitrogen cultivation; 4 - lipids extracted from low carbon cultivation.
