Aspergillus niger ryas macrospours, Aspergillus fumigatus, Penicillium notatum and Penicillium spinulosum were cultured under different cultural conditions. The lipids produced by these species and fatty acid compositions of lipids were investigated. The maximum lipid contents produced by each species were 17.8% for Asp. niger var. macrosporus, 31% for Asp. fumigatus, 12.6% for P. notatum and 17.5% for P. spinulosum, respectively. The major fatty acid compositions were palmitic acid, stearic acid, oleic acid and linoleic acid. Asp. niger var. macrosporus and Asp. fumigatus were highest oleic acid during all incubation periods and P. notatunr and P. spinulsum were linoleic acid. Degree of unsaturation was higher Penicillium than Aspergillus. The fatty acid compositions were changed depending on the incubation temperature, but hardly showed a certain tendency except linoleic acid and degree of unsaturation that were higher at lower temperature.
