We earlier reported that the viability and lipid composition of Mucor hiemalis F-1156 sporangiospores, as well as their capacity to develop yeast-like cells, depend on the age of the spore-forming culture [1]. With the increase in the time of the culture growth, sporangiospores exhibit a decrease in the levels of phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, cardiolipin, and reserve lipids, as well as in the degree of fatty acid unsaturation, whereas the level of glycolipids increases. However, sterol composition was not been studied. Sterols are involved in morphogenetic processes [2, 3], and therefore we suggested that sporangiospores from senescent cultures, which, upon germination, develop mycelium and yeast-like cells, may exhibit a distinctive sterol pattern, along with the changed composition of fatty acids and polar and neutral lipids.
我们之前报道过，毛霉（Mucor hiemalis）F - 1156孢子囊孢子的活力、脂质组成以及它们发育成酵母样细胞的能力，取决于产孢培养物的培养时间[1]。随着培养时间的增加，孢子囊孢子的磷脂酰胆碱、磷脂酰乙醇胺、磷脂酰丝氨酸、心磷脂和储备脂质水平以及脂肪酸不饱和度均降低，而糖脂水平增加。然而，尚未对甾醇组成进行研究。甾醇参与形态发生过程[2, 3]，因此我们推测，来自衰老培养物的孢子囊孢子在萌发时会发育成菌丝体和酵母样细胞，它们可能会呈现出独特的甾醇模式，同时脂肪酸以及极性和中性脂质的组成也会发生变化。
