[Sterols of the fungus Mucor hiemalis sporangiospores].
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.
