摘要:

为发掘、利用西藏野生菌种资源,该研究对采自西藏农牧学院校内的一株野生菌株(JX-1)进行了分离纯化培养,通过形态学和分子生物学进行鉴定,以此为试验菌株,研究该菌的适宜母种培养基以及不同碳源、氮源、无机盐、生长因子、pH值、温度等对该菌菌丝生长的影响,再从中选择4个较优因子进行正交试验。结果表明,JX-1菌株为卷须猴头菌,为西藏新纪录种,其适宜母种培养基为PDA改良培养基+花生粉;该菌株菌丝生长最适碳源、氮源、无机盐和生长因子分别为可溶性淀粉、酵母膏、FeSO4、赖氨酸,最适pH值为4,最适培养温度为20 ℃;正交试验结果表明,最佳配比为碳源可溶性淀粉、氮源牛肉膏、初始pH值为5、生长因子为赖氨酸。研究结果可丰富大型真菌资源,为大型真菌的发掘利用提供有益参考。

Abstract:

To explore and utilize the resources of wild strains in Xizang, in this study, a wild strain (JX-1) from Xizang Agricultural and Animal Husbandry University was isolated, purified, and identified by morphology and molecular biology. Using this strain as the test strain, the optimal parent medium of this strain and the effects of different carbon sources, nitrogen sources, inorganic salts, growth factors, pH value and temperature on the mycelia growth of this strain were studied, and then 4 optimal factors were selected for orthogonal test. The results showed that strain JX-1 was Hericium cirrhatum, a new record species in Xizang, and the most suitable parent medium was PDA modified medium+peanut powder. The optimal carbon source, nitrogen source, inorganic salt and growth factor for mycelium growth of this strain were soluble starch, yeast extract, FeSO4 and lysine, respectively, the optimal pH value was 4, and the optimal culture temperature was 20 ℃. The orthogonal test results showed that the optimal ratio was soluble starch from carbon source and beef extract from nitrogen source, the initial pH value was 5, and the growth factor was lysine. The results can enrich the resources of macrofungi and provide useful reference for the excavation and utilization of macrofungi.
