摘要
目的改良传统的Leeming&Notman培养基,提高马拉色菌的培养效率,并实际应用。方法设立含1%橄榄油、2%橄榄油和4%橄榄油的培养基组。在培养第3、5、7日测量菌落直径,提取基因组DNA并检测浓度,扩增ITS1-2区比较PCR产物质量。结果马拉色菌在含4%橄榄油的培养基上生长最为迅速,产出的基因组DNA量最大,扩增得到的ITS1-2区产物质量最佳。结论改良的含4%橄榄油的Leeming&Notman培养基有利于提高马拉色菌科研工作的效率。
Objective To improve the efficiency of traditional Leeming&Notman culture medium for Malassezia species and put into practical application. Methods Three groups of culture mediums containing 1% ,2% or 4% of olive oil were established for a- nalysis. On the 3rd,5th and 7th day of culturing, the diameter of each colony was measured, the genomic DNA of Malassezia isolates was extracted for quantitative analysis, and the ITS1-2 region was amplified for quality evaluation. Results Malassezia isolates on 4% of ol- ive oil medium grew most rapidly, yielded the greatest amount of genomic DNA, and guaranteed best PCR products of ITS1-2 region. Conclusion Modified culture medium containing 4% of olive oil for Malassezia species is likely to improve the efficiency of research work.
