摘要：

The influence of Ca2+, Mg2+, Mn2+, and Fe2+ ions on lipid accumulation, fatty acid composition and arachidonic acid (ARA) production by Mortierella sp. S-17 was investigated. A beneficial effect of Mn2+ in the concentration range of 2-500 mg/L on lipogenesis was observed. The other elements at about 1 g/L repressed lipid accumulation and ARA yield. The highest yield of ARA (723 mg per liter or 148 mg per gram of dry mycelium) after incubation of the fungus in a glucose medium in the presence of 2 mg Mn2+ per liter was obtained. A strong inhibitory effect of Fe2+ (above 40 mg/L) on ARA formation was observed.
