Phospholipids of M. phlei ATCC 354 are cardiolipin, phosphatidyl ethanolamine, tri- and tetra-acylated dimannophosphoinositide and tetraacylated pentamannophosphoinositide. Contrary to a previous report, monomannophosphoinositide was not evident. A linear decrease in total lipid was observed with an increase in the N content of the medium. An inverse relationship was observed with the C supply in the medium. Cells grown on a medium with limited N contained more saturated fatty acids, whereas cells grown on a medium with limited C contained more unsaturated fatty acids. No significant change in phosphatidyl ethanolamine resulted from changing the C and N supply in the medium. Phosphatidylinositol mannosides were the major phospholipids in glycerol-grown cells, but in glucose-grown cells concentrations of phosphatidylinositol mannosides and cardiolipin were the same. Glyceride content of cells increased with an increase in C supply and decreased with an increase in N supply in the medium. Phosphatidylinositol mannosides were the major phospholipid component at 37.degree. C, whereas cardiolipin was the major phospholipid in cells grown at 27.degree. C. Among fatty acids, a considerable decrease in palmitic acid with a concomitant increase in palmitoleic and oleic acid was observed with a decrease in growth temperature from 37 to 27.degree. C. There is a preferential production of certain lipid constituents under various cultural conditions.
