The fatty acid composition of some entomophthoraceae

Lipids extracted from Conidiobolus denaesporus Drechsl. were found to contain three branched‐chain fatty acids, which together comprised about 35% of the total fatty acids of the fungus. The branchedchain acids were identified by gas‐liquid chromatography, infrared and mass spectroscopy as 12‐methyl tridecanoic, 12‐methyl tetradecanoic, and 14‐methyl pentadecanoic acids respectively. The n ‐saturated acids comprise C12, C13, C14, C16, and C18. The n C16, n C18, and n C20 unsaturated acids were also found. The occurrence of 15.2% of myristic acid and of 8.9% of eicosatetraenoic acid provides a further distinctive feature of the lipids of Conidiobolus denaesporus .
