摘要:

樟芝(Taiwanofungus camphoratus)是我国台湾特有的珍稀药用真菌。本文对1株野生樟芝子实体分离株Ac-NF2进行鉴定,并考察液体培养条件下菌丝培养特性。通过形态学及核糖体DNA内转录间隔区(ITS)系统发育分析鉴定菌株Ac-NF2为樟芝。菌株Ac-NF2液体培养适合的单一碳源为麦芽糖,较优的复合碳源为葡萄糖与麦芽糖组合;适宜的单一氮源为酵母粉,较优的复合氮源为蛋白胨与酵母粉组合。菌株Ac-NF2菌丝生长适宜的pH值为5~6、温度为25~27 ℃。液体培养条件下菌株Ac-NF2易无性产孢,孢子密度达3.2×107 mL-1。本研究丰富了樟芝种质资源,同时为应用该菌株液体发酵生产菌丝体及活性成分提供参考。

Abstract:

Taiwanofungus camphoratus is a precious medicinal fungus endemic in Taiwan,China. This study identified an isolated wild Taiwanofungus camphoratus strain and examined its mycelial growth characteristics under liquid culture conditions. Morphological and ITS(Internal Transcribed Spacer)phylogenetic analysis identified the strain Ac-NF2 as Taiwanofungus camphoratus. For strain Ac-NF2,the suitable single carbon source in liquid culture was maltose,while the optimal combined carbon source was a combination of glucose and maltose. The appropriate single nitrogen source was yeast extract,and the preferred combined nitrogen source was a combination of peptone and yeast extract. The optimal pH value of the medium was between 5 and 6,and the temperature range of 25 and 27 ℃ was desirable for the mycelial growth. The strain produced easily asexual spores in liquid cultures,and the density of asexual spores reached 3.2×107 mL-1. The present study not only broadened the germplasm source of Taiwanofungus camphoratus,but also provided reference for the application of this strain in liquid fermentation production of mycelium and active ingredients.

Key words: Taiwanofungus camphoratus, strain identification, carbon source, nitrogen source, asexual spore
