The fungus Mucor hiemalis F-1156, which is believed to be monomorphic, was found to be able to grow dimorphically in a liquid medium that is free of chemical agents influencing morphogenesis. The growing mycelium produced arthrospores in large amounts. The lipids of the mycelium, yeastlike budding cells, and arthrospores differed in the contents of saturated and unsaturated fatty acids and in the proportion of polar and neutral lipids. The arthrospores contained more monoenoic fatty acids in the total lipids, more triacylglycerides and sterol esters in the neutral lipids, and more phosphatidylcholine and phosphatidylethanolamine in the polar lipids than the yeastlike cells. These differences in the lipid composition of different types of fungal cells should be taken into account in the studies of the lipogenesis of M. hiemalis.
被认为是单态的毛霉属真菌冬生毛霉F-1156，被发现能够在不含影响形态发生的化学试剂的液体培养基中进行双态生长。生长的菌丝体产生了大量的节孢子。菌丝体、酵母样芽殖细胞和节孢子的脂质在饱和脂肪酸和不饱和脂肪酸含量以及极性脂质和中性脂质比例方面存在差异。与酵母样细胞相比，节孢子在总脂质中含有更多的单烯脂肪酸，在中性脂质中含有更多的三酰甘油和甾醇酯，在极性脂质中含有更多的磷脂酰胆碱和磷脂酰乙醇胺。在冬生毛霉脂肪生成的研究中，应考虑不同类型真菌细胞脂质组成的这些差异。
