We studied viability of sporangiospores from a surface culture of the fungus Mucor lusitanicus 12M grown on wheat bran. With culture ageing, the sporangiospores exhibited a tendency toward dimorphic growth upon germination and then lost the ability to germinate. This correlated with changes in the sporangiospore lipid composition, which involved a reduction in the total lipid pool and in the levels of reserve lipids and phospholipids in particular. We suggest that lipid catabolism in sporangiospores causes their defectiveness in the senescent culture.
我们研究了在麦麸上生长的葡萄牙毛霉12M表面培养物中孢子囊孢子的活力。随着培养时间的延长，孢子囊孢子在萌发时呈现出双态生长的趋势，随后失去了萌发能力。这与孢子囊孢子脂质组成的变化相关，其中包括总脂质库的减少，尤其是储备脂质和磷脂水平的降低。我们认为，孢子囊孢子中的脂质分解代谢导致了它们在衰老培养物中的缺陷。
