中国毁丝霉属两个新记录种

Two new records of the genus Myceliophthora in China

摘要:

【目的】对我国西部地区土壤中嗜热毁丝霉属真菌资源进行调查。【方法】采集西部地区各省市不同环境的土壤样品，采用富集培养法，从土样中分离毁丝霉属菌株；再采用经典形态学及分子系统学方法相结合对获得的菌株进行鉴定。【结果】共从采集的样品中分离获得12株毁丝霉属菌株，其中G10菌株为异宗毁丝霉Myceliophthora heterothallica，EB6301M菌株为棉毛毁丝霉Myceliophthora vellerea，其余10株菌为嗜热毁丝霉Myceliophthora thermophila。【结论】棉毛毁丝霉和异宗毁丝霉均为我国新记录种。

Abstract:

[Objective] The objectives were to study and discover thermophilic fungi from soil in western China. [Methods] Different environmental and regional soil samples were collected and cultivated by the enrichment culture using feather. The strains of the genus Myceliophthora were isolated and identified by the classical morphological characters and molecular systematics. [Results] Strain G10 was identified as Myceliophthora heterothallica; EB6301M was M. vellerea and other ten strains were M. thermophile. [Conclusion] M. heterothallica and M. vellerea were two new record species in China.
