^aThe table shows data from three independent experiments.

^bPercentage of total fatty acids.

^cND, not detected.

^dInternal lipids were extracted from cells grown in minimal medium supplemented with the appropriate carbon source for 20 h. Fatty acids were analyzed by gas chromatography.

^etr, found in trace amounts.
