1株产色素毛壳菌的分离鉴定及其生物学特性

Isolation, Identification and Biological Characteristics of Chaetomium sp. of Produce Red Pigment

    摘要
  • 摘要: 为筛选出能够产生色素的真菌，采用组织分离法从核桃枝干上分离鉴定出1株产天然红色素的毛壳菌属真菌YLHT−2A，通过形态学和ITS分子方法对菌株进行鉴定，并对菌株YLHT−2A的生物学特性进行研究。结果表明：菌株YLHT−2A鉴定为金色毛壳（Chaetomium aureum）；该菌株最佳培养基为PDA培养基，最佳培养温度是30 ℃，最佳生长光照条件是24 h全黑暗，最佳生长pH为10。

     

    Abstract: To screen out fungi that produce pigments, a natural red pigment-producing fungus YLHT−2A was isolated from walnut branch by tissue separation method. The strain was identified by morphology and ITS molecular series analysis, and biological characteristics of strain YLHT−2A were studied. The findings indicated that the strain YLHT−2A was identified as Chaetomium aureum. The optimal medium of the strain was optimized as PDA medium by experiments, and the optimum culture conditions were 30 ℃, 24 h darkness, pH 10.
