The lipid productivities of five species (9 strains) of genus Pellicularia in Bacidiomycetes obtained from the Institute for Fermentation, Osaka, were investigated. The lipid extracts of the stationary phase cells cultivated by stationary culture method were fractionated into neutral and polar lipid fractions by silicic acid column chromatography. The fatty acid compositions of both lipid fractions were determined by gas liquid chromatography. Futhermore, the lipid compositions of both fractions were quantitatively determined. It is found that the lipid productivities and the contents of total cellular lipids of the genus Pellicularia, varied among the strains, but the levels of linoleic acid in their total lipids are commonly high in any case. The lipid productivities of four species (5 strains) of the genus Pellicularia cultivated by shaking culture were also investigated. It was observed that the levels of linoleic acid in the lipids were high not only in the case of usage of glucose as a carbon source, but also in the case of usage of cellulose.
