摘要: 目的 探讨常见病原性丝状真菌的菌种保藏方法。方法 将73株病原性丝状真菌经过纯化后,接种于马铃薯葡萄糖琼脂斜面分别在4℃和-80℃冷冻管保存,均用10%(v/v)的丙三醇作为保护剂。结果 经过1 a左右的保存,将菌株复活,发现4℃斜面保藏法菌株的存活率为100%,-80℃冷冻管保藏法菌株的存活率为98.6%,有些毛癣菌属的菌株不耐低温而不适合-80℃保藏。结论 病原真菌可以合理地结合上述2种方法保藏。若实验室配有低温冰箱,可以-80℃冷冻管保藏法为主,对于某些不耐低温的丝状真菌需要同时采用4℃斜面保藏法,则可以保证菌种的存活率。

Abstract: Objective To explore a practical and effective method for fingi preservation.Methods Seventy-three strains of pathogenic filamentous fungi were preserved on Potato dextrose agar slants at 4℃ and in freezing tubes at-80℃,overlaid with 10%(v/v) glycerol after purification.Results The survival ratioes were 98.6% at -80℃ and 100% at 4℃ after one-year preservation.Conclusions These two methods are simple,convenient,and valueble in preservation of pathogenic filamentous fungi.
