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.

Key words: Hericium cirrhatum, new record species, macro fungi, biological characteristic
