Abstract: Mortierella isabellina was found to accumulate lipid with 2% hexadecanol and 1% yeast extract as the growth substrates. The amount of lipid reached 64.5% of dry mycelia, and unsaturated acids accounted for 97.05% of the total fatty acids. Mean while, 75% of hexadecanol in medium was converted to lipid. The biosynthetic route from hexadecanol to linoleic acid was presumed as follows: Hexadecanol——C18∶0(Steric acid)——C18∶1(Oleic acid)——C18∶2(Linoleic acid)
