Fifteen strains of filamentous fungi from the Culture Collection of Fungi (Charles University, Prague) were tested for their lipid production, fatty acid composition with emphasis on accumulation of oligounsaturated fatty acids. All cultures contained palmitic (16:0), palmitoleic (16:1), stearic (18:0), oleic (18:1), linoleic (18:2) and gamma-linolenic (18:3) acid (GLA). The mycelium of Cunninghamella elegans, Rhizopus arrhizus, Mortierella parvispora, M. elongata and M. alpina contained arachidonic acid (ARA) in the range of 2.3-33.5% of the total fatty acids. The strains used in our experiment were capable to accumulate a relatively high amount of intracellular lipid (9.6-20.1% in dry biomass). The highest content of GLA (22.3 mg/g) was found in Mucor circinelloides. The strain of M. alpina containing 47.1 mg/g of ARA could be considered as the best producer of ARA.
对来自真菌培养物保藏中心（布拉格查理大学）的15株丝状真菌进行了脂质产量、脂肪酸组成测试，重点是低不饱和脂肪酸的积累情况。所有培养物均含有棕榈酸（16:0）、棕榈油酸（16:1）、硬脂酸（18:0）、油酸（18:1）、亚油酸（18:2）和γ-亚麻酸（18:3）（GLA）。雅致小克银汉霉、少根根霉、小孢被孢霉、伸长被孢霉和高山被孢霉的菌丝体中花生四烯酸（ARA）含量占总脂肪酸的2.3%-33.5%。我们实验中使用的菌株能够积累相对大量的细胞内脂质（占干生物量的9.6%-20.1%）。在卷枝毛霉中发现GLA含量最高（22.3毫克/克）。含有47.1毫克/克ARA的高山被孢霉菌株可被视为ARA的最佳生产者。
