| 目的：在对嗜热真菌的资源调查中，分离到嗜热真菌20 株。方法：通过形态学比较研究并结合分子分析方法。结果：鉴定出
嗜热真菌4 种，即杜邦青霉Penicillium dupontii、疏绵状嗜热丝孢菌Thermomyces lanuginosus、嗜热子囊菌Thermoascus aurantiacus、
嗜热革节孢Scytalidium thermophilum。此外，还分离到耐热真菌1 种，鉴定为不规则头梗霉Cephaliophora irregularis，为中国新记
录种。结论：这些研究结果新增了嗜热真菌在中国的分布记载，丰富了我国西南地区嗜热真菌的菌种资源库，另外对分离获得的
嗜热真菌进行木聚糖酶活性测试，发现嗜热子囊菌为高产木聚糖酶活力的菌株。 |

| Objective: To investigate and identify the species of thermophilic fungi according to morphology characteristic
and identification.Methods：The illustrated description of specieswas supplied. Results：Four species of thermorphilic fungiwere identified,
among of them, including Penicillium dupontii, Thermomyces lanuginosus, Thermoascus aurantiacus and Scytalidium thermophilum.
One thermotolarent fungus was also isolated and identified, that is Cephaliophora irregularis, which become new record for the first time
in China. Conclusion: Among of the obtained strains, Thermoascus aurantiacus Gxu03 was the best strain producing the highest xylanase
activity. |
